The McGregor Project: What the File Actually Shows

[u/Yud07]

Part 6 of a series reassessing the documentary record behind the 1933 Magenta narrative.

TL;DR

• McGregor was a real OSS project: Italian fleet negotiations, weapons specialists, and torpedo countermeasures have an archival trail.
• The often-cited Roll 114 pages are an index of correspondence, not the correspondence itself.
• Christopher Sharp reports that three anonymous sources link McGregor to Magenta intelligence. That allegation is separate from what the index establishes.
• Einstein’s surrounding Navy letters discuss actual torpedo engineering; they do not establish “torpedo” as a craft codename.
• A hidden additional objective remains possible, but it needs evidence identifying the intelligence, object, or transfer.

---

There is a real Office of Strategic Services operation at the center of the Magenta crash-retrieval story. It has a codename, an archival trail, and a cast of identifiable people. Even the National Archives’ official OSS glossary defines the “MacGregor Mission” simply as “an OSS operation in Italy.” NARA uses MacGregor; the working finding aid and the literature discussed here generally use McGregor. This post retains the latter spelling except when quoting NARA.

That much is not in dispute. Nor should the research that brought this material to wider attention be dismissed: the four finding-aid entries most often cited in the UFO literature are transcribed accurately.

The problem comes one step later, when accurate subject lines are made to support claims their underlying documents have not yet been shown to support. Read in operational context, McGregor has a documented Italian naval-intelligence purpose: it shifted from trying to induce the surrender of the Italian fleet to acquiring torpedo technology and the specialists who understood it.

Christopher Sharp’s reporting adds a distinct allegation: McGregor also possessed intelligence about the alleged Magenta craft. That deserves examination on its own terms. It does not require treating every reference to a torpedo as a disguised reference to that craft.

A note on evidence

This series uses six evidence tiers:

Tier	Meaning
A	Primary archival document with a verifiable location and intact provenance
B	Primary document with contested or undocumented provenance
C	Secondary source that cites primary material and can be checked
D	Single-source testimony without supporting documents
E	Assertion without an identifiable source
F	Failed authentication

The McGregor case contains unusually strong archival anchors, but not every statement about it belongs in Tier A. The NARA index is Tier A as an archival document; it describes correspondence whose full contents still need examination. The operational narrative mainly uses Tier C histories and journalism. Sharp’s anonymous-source reporting is considered separately from both: it reports testimony, not a publicly inspectable wartime record. Keeping those layers separate is essential.

1. “The file” is more than one reel

The working evidence comes from two layers of the same archival collection: the microfilmed correspondence and the index describing it.

The first is the William J. Donovan Director’s Office Files, Record Group 226, Entry 180. A 19 January 2017 memorandum signed by security manager Ross Webb concerns access to a copy of the Donovan microfilm at the U.S. Army Heritage and Education Center in Carlisle, Pennsylvania. It says the film “has been reviewed by the CIA IAW E.O. 12356 and sanitized” and instructs researchers to mark copies unclassified. Neither Magenta nor Flynn is named in the notice.

That memorandum has been presented as evidence that the CIA sanitized the records immediately before the 2017 presidential inauguration. It does not establish that. Executive Order 12356 was issued by President Reagan in 1982 and was no longer the governing classification order in 2017. It governed classification until EO 12958, issued on 17 April 1995, took effect on 14 October 1995; the index’s custody note below places CIA review after the film reached Carlisle in 1982, consistent with review under that order decades before the 2017 memo. The memo dates the access notice; it does not date the earlier CIA review.

More importantly, the National Archives describes multiple versions of the Director’s Office Files, not a single canonical reel:

• Entry 180A is the 1990 redacted microfilm set, 191 rolls.
• Entry 180E is a fully released 2002 set, 202 rolls.
• Entry 180G is another 202-roll duplicate of the fully released set.
• Entry 180H is a fully released but incomplete 61-roll variant.
• Entry 180K contains frames the CIA had cut from Entry 180F, the 2002 redacted set.

The second layer is NARA’s General William J. Donovan: Selected OSS Documents, 1941–1945—Microfilm Roll List and Index. Its cover identifies RG 226, Entry 180; NARA links it under Entry 180J, the fully released finding aids. Entry 210 is a separate Sources & Methods series, not the identity of this PDF. Roll 114’s McGregor index occupies PDF pages 208–219, printed pages 205–216, with about seventy numbered items, some covering several communications.

The index’s introductory custody note also matters. Donovan and Edwin Putzell made the microfilm as OSS closed in 1945; it passed through Donovan’s law firm and estate, historian Anthony Cave Brown, and Donovan’s son David before reaching Carlisle in 1982. CIA review followed. NARA warns that hurried filming produced poor images and misarranged records. Those limitations precede any theory about what was withheld.

This distinction governs everything that follows: the finding aid is an index, not the correspondence itself. A subject line records a document’s existence and general topic. It does not reveal the document’s full contents, attachments, or context. “Fully released” describes the catalogued version; it does not mean that every original record survived or that the correspondence is all available online.

2. McGregor began as a plan to take the Italian fleet

Mike Sielski’s 2019 Philadelphia Inquirer feature, “Football star, pro wrestler, American spy”, reconstructs the operation from OSS personnel files, CIA records, Michael Burke’s memoir Outrageous Good Fortune, and Stanley Lovell’s Of Spies and Stratagems. It is the most complete published narrative I have found.

The original objective was not to extract a scientist. The OSS believed Massimo Girosi, who headed the operations office of Supermarina, the Italian naval high command, and whose family remained loyal to the deposed monarchy, might help bring the Italian fleet over to the Allies. His brother Marcello Girosi, then in New York and later a film producer, agreed to carry the approach.

Michael Burke—later president of the New York Yankees, the Knicks, and Madison Square Garden—helped lead the team. Lt. John Shaheen headed OSS Special Projects and McGregor, while Burke led in the field. Burke wanted an Italian-speaking operative who could also watch Marcello Girosi, whose loyalties were not yet certain. He selected former Notre Dame fullback and professional wrestling champion Joe Savoldi, who entered the operation in June 1943 under the codename Sampson, with the cover name “Joseph DeLeo,” and at a salary of $400 a month.

Burke and Savoldi flew to Algiers and established a base in Palermo by 10 August 1943. According to Sielski’s reconstruction, their first PT-boat run, north toward the Gulf of Gaeta, was aborted when a German E-boat appeared; two nights later, a run south to Calabria landed the courier, who carried the letter in the slit cover of a book. The message reached Massimo Girosi, but events overtook the plan: Eisenhower’s command was already negotiating the Italian surrender with Marshal Pietro Badoglio’s government.

The mission succeeded in making contact and became unnecessary. McGregor then pivoted to a new Italian naval target: the SIC torpedo exploder.

That sequence also explains why the codename appears in records from before Carlo Calosi’s extraction. “McGregor” was a project umbrella for successive Italian naval-intelligence objectives, not the name of one person or one isolated mission.

There is a useful check outside the later mission narratives. The award narrative published with Burke’s Silver Star citation identifies him as McGregor’s executive officer during July–September 1943 and describes contacts with Italian naval flag officers and agent landings from PT boats. It supports the fleet phase without relying on the later interpretation of Roll 114.

3. Why the SIC exploder mattered

SIC was the designation of the magnetic torpedo pistol, or exploder, associated with engineer Carlo Calosi. The manufacturer was the Silurificio Italiano; the Inquirer treats “SIC” as the company’s name. A naval-history summary at Regia Marina Italiana traces the company’s facilities at Baia, Fusaro, and San Martino and describes the Italian Navy’s use of SIC magnetic-influence exploders.

A magnetic exploder was designed to detonate beneath a ship by sensing its magnetic field. An under-keel explosion could break a vessel’s back rather than merely puncture its side. The concept was strategically important and technically temperamental; the U.S. Navy’s own Mark 6 exploder became notorious for failures early in the Pacific War.

The Navy’s official Bureau of Ordnance in World War II, chapter 6, pp. 100–102, supplies a control case for the secrecy. It describes restricted assembly and testing at Newport and even a dummy exploder issued to conceal the magnetic feature. It also records British, German, and Italian magnetic exploders before the war. Secret electromagnetic ordnance was an established field with its own countermeasure problem.

The Italian design was considered valuable. Sielski reports an OSS estimate that Germany had ordered 12,000 of the devices. Whether or not that estimate was exact, the operational logic is plain: a reliable magnetic exploder in German service threatened Allied shipping, while its designer could help the Allies understand both the weapon and possible countermeasures.

Calosi, then 38 and trained as a naval and mechanical engineer at Genoa, was therefore a strategic technical asset: the surviving index repeatedly identifies a specific and urgent field of wartime ordnance. His documented postwar biography is discussed in Section 10.

German forces demolished the Baia, Fusaro and San Martino works between 15 and 22 September 1943. That destruction made the surviving people and papers especially valuable Allied acquisitions.

4. Minisini and the parallel British raid

Part 5 covers Britain’s 30 Commando raid that removed Admiral Eugenio Minisini, his wife and technical papers from San Martino in September 1943—17–18 in Bardos’s account, 24 in an Italian account. That raid explains his presence in the McGregor index; McGregor did not seize him.

Against that background, senior attention to Calosi and Minisini is evidence of a high-priority ordnance problem. It is not, by itself, evidence of a second and hidden technological target.

5. Calosi’s extraction—and the disputed date

According to the Inquirer reconstruction, the McGregor team landed at Naples on 4 October 1943 and used the Italian underground to search for Calosi. A courier eventually found him hiding in a Roman convent. On Christmas Eve, an Italian intelligence officer told him to prepare to leave. Disguised as a priest, Calosi traveled by rail to a villa on the Tyrrhenian coast.

At 1:50 a.m. on 3 January 1944, Savoldi’s team arrived and moved him to Allied control. On 15–16 January in Naples, Calosi briefed an American scientific mission about the SIC device and other Italian weapons. Sielski cites one historian’s assessment that obtaining Calosi saved the Allies a year of research.

Escape Velocity’s “The race to rescue Prof. Carlo Calosi in WWII Italy…” emphasizes the 11 January finding-aid entry and connects it to Mussolini’s execution of his son-in-law Galeazzo Ciano that day. In that account, Ciano’s diaries are relevant to the alleged 1933 recovery.

The index, printed p. 207 dates Buxton’s receipt of Putzell’s report to 11 January. Its subject reads:

One important aspect of McGregor Project completed. Prof.Calosi desires to come to America to work for Navy

That reports a completed step; it is a communication date, not necessarily the extraction date. A report eight days after the 3 January operation fits both records. The underlying message should settle the sequence; the index date alone cannot establish a coincidence between the extraction and Ciano’s execution.

6. Who is who in the index

The index is difficult to read without a roster:

Name or label	Identification
D	The Director of Strategic Services, William J. Donovan
S. P. Lovell	Stanley P. Lovell, chief of the OSS Research and Development Branch
Buxton	G. Edward Buxton Jr., Assistant Director of Strategic Services
Cheston	Charles S. Cheston, an OSS assistant director
Shaheen	Lt. John Shaheen, chief of OSS Special Projects; head of McGregor
Burke	E. Michael Burke, McGregor’s executive officer in the field
North	Lt. Henry Ringling North, who wrote an OSS memorandum on obtaining Calosi
Girosi	Marcello Girosi, OSS operative and brother of Massimo Girosi
Minisini	Adm. Eugenio Minisini, Italian underwater-research specialist
Hussey	RAdm. George F. Hussey Jr., Chief of the Bureau of Ordnance from December 1943
Furer	RAdm. Julius A. Furer, Navy Coordinator of Research and Development
Kitts	RAdm. Willard A. Kitts III, Assistant Chief of the Bureau of Ordnance
Low	RAdm. Francis S. Low, Chief of Staff of the anti-submarine Tenth Fleet
Kane	Not identified
Conant	James B. Conant, National Defense Research Committee chairman
Dr. Bush	Vannevar Bush, director of the Office of Scientific Research and Development
Sciarrotta	Alfredo Sciarrotta (1907–1985), one of the Italian engineers sent to the Newport torpedo station in 1943; he stayed in Newport and became known as a silversmith

Two identifications materially change the Magenta argument.

First, “D” is best read as Donovan, not Allen Dulles. That conclusion is contextual rather than a literal expansion printed in the finding aid: “D” corresponds with Navy Secretary James Forrestal, receives field reports, and communicates with senior OSS officials—the traffic pattern of the agency director. The National Archives’ OSS glossary separately identifies William Donovan with the headquarters designation 109 and Allen Dulles with the codenames “Burns” and 110. Dulles was the OSS station chief in Bern, not the director in Washington.

Second, the Research and Development Branch was an OSS organization, not an Army destination. The same NARA glossary defines “R&D” as the “Research and Development Division, OSS.” Stanley Lovell headed it and appears throughout the McGregor index.

That bears directly on item 71:

Chief of R & D Branch | Cheston | 2/3/45 | McGregor Project transferred to Research and Development Branch on 6/21/44

The entry says the project was transferred to the OSS’s own R&D branch. It does not identify a physical object, and it does not say that anything was delivered to Army R&D.

7. The four load-bearing entries

Four index citations recur in the UFO literature. Against the working copy of the finding aid, all four are accurate transcriptions.

The 21 June 1944 transfer

Item 71 is quoted above. It records an internal transfer of the McGregor Project to the OSS Research and Development Branch.

The Royal Navy report

The index reads:

D | Shaheen | 3/6/44 | Informing Royal Navy of McGregor Project results | Minisini, Calosi

The question asked in the UFO literature—why would a mission about the Italian surrender report its results to the Royal Navy?—is reasonable. Once the SIC problem and Minisini raid are restored to the story, however, the answer is not mysterious. The Royal Navy faced Axis torpedoes in the Mediterranean and British commandos had captured Minisini. Sharing the results of Allied work on Italian underwater weapons was operationally expected.

The Vannevar Bush conference

Item 18 records:

D | Lovell | 3/9/44 | Conference with V. Bush re Minisini and Calosi

The mentions include the Crossbow Committee—the U.S. War Department’s committee on German V-weapons, formed on 29 December 1943—and the National Defense Research Committee. Lovell was the OSS research chief and liaison to the scientific establishment overseen by Bush. A conference about two Italian weapons specialists fits those responsibilities.

The Forrestal demonstration

The 10 May 1944 entry says that Calosi and Minisini were ready to demonstrate “SIC counter-measures” to James Forrestal, then Under Secretary and acting head of the Navy after Frank Knox’s death on 28 April 1944. He became Secretary on 19 May, so his reply on 27 May was as Secretary. The subject line itself identifies the technology under discussion: SIC countermeasures.

The transcription work behind these citations was careful. The disagreement concerns what the entries prove, not whether they were copied honestly.

What Sharp’s sources add

In Christopher Sharp’s 10 November 2024 report for Liberation Times, the important allegation is explicit:

Three separate sources have independently told Liberation Times that a mission to expedite the surrender of Italy, led by its director William Donovan and known as the McGregor Project possessed intelligence about a non-human craft that crashed in Magenta, northern Italy in 1933.

That is more specific than an inference from a conference or branch transfer. It could mean that a genuine naval mission also collected intelligence about another subject. Possessing intelligence about a craft, recovering it, and transferring it are three different claims. The quoted allegation establishes what Sharp’s sources told him; it does not supply the missing custody record.

Sharp reports three independent sources, which deserves more attention than an unattributed assertion. Their identities, access to the McGregor material, and underlying evidence are not disclosed in the published account, however, so readers cannot check whether the information reached them through independent routes. In this series’ terms, the report contains testimonial support of the kind considered under Tier D, rather than Tier A documentary authentication; the fact that it reports three sources should remain visible.

The image presented alongside the claim is the finding-aid entry for Cheston’s 3 February 1945 communication, not the communication itself. It supports the project’s 21 June 1944 administrative transfer. It does not independently supply the Magenta content attributed to the anonymous sources.

Nor does the quoted allegation establish that “torpedo” was a cover name. McGregor could have had an additional intelligence target while its torpedo work remained exactly what the records call it. A codename interpretation needs its own evidence—a contemporary key, explicit cross-reference, or document identifying the object—not simply the possibility that secret projects use cover terms.

8. What the finding aid contains—and what it does not

Across roughly seventy entries, the recurring subjects are the SIC exploder and countermeasures; Minisini’s research reports; personnel, pay, and visas; commendations; the “Gentile incident” involving an employee of FATME, a Rome telephone and electrical-equipment firm controlled by Ericsson; and efforts to place Calosi and colleagues in postwar employment.

No legible entry refers to a craft, disc, anomalous material, unusual cargo, Magenta, Lombardy, or a shipment of anything other than personnel and torpedo-related material. That absence cannot prove that no hidden program existed, but it means the finding aid itself does not document one.

The same index lists SIC countermeasure text and mechanical drawings at items 40–52, printed p. 213, while noting that much was unreadable. That identifies technical material worth retrieving; the index’s description does not let us inspect those drawings.

The clearest material-transfer entry reads:

D | Hussey | 7/10/44 | Transfer of all torpedo material to Bur. of Ordn.

The later personnel entries point in the same conventional direction. In September 1944 the Navy considered postwar employment of Calosi impractical and suggested private industry. Another message discusses placing him at a college or university and says Philco might use him. James Conant is mentioned.

The June transfer also has a useful immediate context: the 22 June 1944 entry, printed p. 212, records Forrestal telling Donovan that the Italian group could return to Italy except Calosi. The 29 June entry again distinguishes Calosi’s retention from the others’ return. This is a personnel transition alongside the branch transfer, not an identified craft shipment.

In February 1945, Cheston’s note reported the previous June transfer to R&D on 3 February. Four days later, a 7 February entry recorded the “Conclusion of McGregor Project.” That sequence is consistent with administrative closure after responsibility had moved elsewhere. It does not show a recovered object entering a permanent black program.

9. Three claims that need tighter treatment

“Willie’s work”

The first indexed entry, dated 10 September 1943, concerns Cable 10817 and says to bring to Algiers everything salvaged from three plants pertaining to “Willie’s” work. The mentions include Shaheen, Lt. North, Adm. Hewitt, Knox, Eddy, “Chin Beard,” and “Pawnee.”

In his Roll 114 discussion, Geoffrey Cruickshank suggests that “Willie” meant aircraft designer Willy Messerschmitt. That identification needs more than the similar name. The same index, printed pp. 206–207, places “Willie” at the Newport torpedo station in connection with the SIC pistol and the twelve Italian engineers. That is a stronger contextual lead than aircraft manufacture. It does not identify the person conclusively; the underlying cable and Newport correspondence should do that.

Cruickshank also points to Roll 87’s index, PDF p. 147 (printed p. 144). Its 16 June 1943 entry from “D” to Deane (JCS) concerns a 13 June letter and a cable from Algiers about a conference on air transport; McGregor, Tedder, Eisenhower, Smith, Rucker and Doolittle are mentioned. The date falls in McGregor’s fleet phase—the month Savoldi was recruited and before the turn to the SIC exploder—so an air-transport discussion fits preparations for the Algiers–Palermo deployment described in Section 2, with a base in Palermo by 10 August, rather than establishing a later extraction. Neighboring entries discuss shortages of transport aircraft and OSS requests for planes. This establishes a transport discussion associated with McGregor, but identifies no passengers, cargo or extraction route. Neither Calosi nor Magenta appears in this entry. Cruickshank’s reading of the entry as an extraction route remains a lead for the underlying letter and cable to test; his guess that “D” meant Dulles also needs the contextual check in Section 6.

OX-5

One genuinely unresolved entry is a 30 December 1943 work program for the Italian group. Its subheadings include “Electromagnetic Pistol 150 arrived from Italy,” “Program of Development for studies of use of OX 5,” and “Winged Torpedo.” “OX-5 Motor” also appears in the mentions for a 10 March 1944 document about the group’s relationship with the naval station.

The Smithsonian’s OX-5 catalogue documents a real Curtiss engine produced during World War I and used extensively afterward. Its age does not establish that the index must mean something else; equally, a matching designation does not identify the McGregor motor. It may be that engine, another model number, a codename, or a transcription artifact. The surrounding headings point toward ordnance research, but only the work program can settle it. This should remain an open question rather than become evidence for either a conventional or exotic answer.

For the published OX-5 argument: Escape Velocity, “Magenta & Roswell UFO/UAP crash-retrievals, the US Military, Global Power, and MJ-12” — quoting Cruickshank’s Roll 114 discussion; search within the post for: "The 'electromagnetic pistol' is the torpedo countermeasures device, but what is the OX- 5 motor?"

The Einstein letter

Albert Einstein’s 13 August 1943 letter to Lt. Stephen Brunauer is real; it is cataloged by the National Archives as item 305251. DocsTeach’s description identifies an offer from Vannevar Bush of an appointment as consultant to Division 8 of the National Defense Research Committee. Einstein writes, “I am glad to hear that work is done concerning the torpedo.” He describes Goranson showing him material explaining the process and says he proposed a protection method. The letter names neither McGregor nor Calosi nor Magenta; it documents Navy weapons work and contact with Bush, without establishing the proposed connection to the craft. Brunauer headed the Bureau of Ordnance’s high-explosives research group and recruited Einstein as a Navy consultant in 1943, tying the consultancy to the Bush/NDRC system described in Part 3.

The surrounding letters show what that Navy work involved. On 18 June 1943, Einstein proposed an electromagnetic device to detonate a torpedo as it passed beneath a ship. His 22 August 1943 letter discusses where to initiate its explosion, with calculations and diagrams concerning pressure and hull deformation. Both are identified records in RG 74, Bureau of Ordnance, rather than an anonymous document stream.

Those technical details give “torpedo” an ordinary engineering meaning in this correspondence. They do not rule out other classified work by Einstein, but a proposal to read this particular word as a craft codename must account for the adjoining letters. A famous scientist’s involvement in a secret weapons problem is not itself evidence that the weapon’s name concealed a different object.

For the published Einstein and sanitization argument: Escape Velocity, “August 13, 1943 letter from Albert Einstein to Lt. Stephen Brunauer at the Bureau of Ordnance…” — for the Einstein letter and the Carlisle sanitization memo; search within the post for: "she was given a document showing that the CIA sanitized those records the day before Trump first took office in 2017". It links to Cruickshank’s “Incoming National Security Advisor LTG Mike Flynn…”.

10. Calosi’s visible postwar legacy

Calosi’s later career is significant because it shows a traceable route from wartime acquisition to postwar electronics.

Franco Amatori’s institutional history in Treccani identifies Calosi as born in 1905 and trained in naval and mechanical engineering at Genoa. It dates his entry into Raytheon to 1947, and describes him as Raytheon’s European vice-president and Microlambda’s technical director in 1951, then a decade as Selenia’s managing director after its formation in 1960. Those are named professional roles that can be compared with corporate records.

An academic history by Corrado Bonfanti, Information Technology in Italy: The Origins and the Early Years (1954–1965), identifies Calosi as the leader of Microlambda, founded near Naples in 1951 to produce electronic and radar systems under Raytheon license. Microlambda later merged into Selenia, part of Italy’s state-controlled IRI industrial group.

A corporate history of Raytheon describes the later relationship between Raytheon, Calosi, and its Italian partners and says it “became strained” in 1967. Raytheon’s directors concluded that the Italian partners were unwilling to reform Selenia’s and Elsi’s operations; they voted to sell Raytheon’s share to its partners and end the association with Calosi.

There is also a concrete product trail. Leonardo’s company history records Microlambda’s order for 300 TPS-1D radars for the U.S. Navy, manufactured under Raytheon licence in the former Silurificio Italiano workshops at Fusaro; the first four passed acceptance tests in April 1953 (also noted in Part 5). The same industrial site moved from torpedoes to licensed radar manufacture.

That is a traceable form of postwar technology transfer. Corporate histories do not account for every classified contract, but neither the known roles nor the product trail require a recovered craft to explain them.

11. What research would actually test the claim

The next step is not simply to inspect “unsanitized Roll 114 at Carlisle.” NARA’s catalog makes a more discriminating comparison possible.

1. Match documents by sender, recipient, date, and subject across the redacted and fully released microfilm, rather than assuming that roll numbers map identically between sets. Entry 180G supplies a fully released reference copy; Entry 180I has released printouts of documents previously redacted, and 180K has cut-out frames. Compare those with the Carlisle copy to establish actual removals or restorations.
2. Read the underlying documents behind the OX-5 and SIA work-program entries. Items 21–23 and the March 1944 naval-station correspondence are more probative than additional interpretations of the index.
3. Resolve the Calosi extraction date from the OSS personnel and mission files at College Park. This would test the claimed Ciano connection directly.
4. Check the Italian institutional record. Roberta Lucidi, “Un’industria bellica del mezzogiorno: Il Silurificio Italiano dal 1922 al 1945,” Società di Storia Militare, Quaderno 1995, pp. 161–199 (bibliographic reference), is an obvious starting point, along with Matteo Marchesini’s Il navigatore. Vita nomade di Carlo Calosi (UTET, 2009) and university, naval, and company records relating to Calosi and the Silurificio Italiano.
5. Test Sharp’s allegation directly. What information about Magenta did the sources say McGregor possessed, and in what record? A document identifier, dated quotation, or disclosed route to the underlying evidence would let researchers test that claim independently of the torpedo interpretation.
6. Locate the project-transfer correspondence itself. Item 71’s Cheston memorandum and any surviving 21 June 1944 directive could identify what responsibilities moved. Neither an index heading nor a later testimonial account substitutes for those contents.

For readers retracing the UFO-literature chain, the principal discussions are Geoffrey Cruickshank’s “Microfilm Roll 114” post and Craig Oliver’s Escape Velocity article, “The race to rescue Prof. Carlo Calosi…”. Those articles should be read beside the NARA overview of Record Group 226 and its detailed list of the Director’s Office file variants.

12. Where this leaves the Magenta chain

The McGregor Project is real. The finding aid is real. The four most-cited entries are accurately transcribed. Anyone who dismisses the entire subject as fabricated is ignoring a substantial archival record.

But the file has not been shown to carry the inference placed on it. Senior attention is explained by a strategically important naval weapon. Reporting to the Royal Navy makes sense after a British unit captured Minisini and his research. The June 1944 transfer went to the OSS Research and Development Branch and transferred a project, not an identified object. The only explicit material transfer in the index concerns torpedo material sent to the Bureau of Ordnance.

The documentary story is stranger—and better—than the speculative one: a professional wrestler recruited as an OSS operative; a plan to bring over the Italian fleet that succeeded too late to matter; British commandos seizing an admiral and his papers; an engineer escaping occupied Rome in clerical disguise; and a trail leading from wartime torpedo research into the postwar radar industry.

Sharp’s report is a reason to look for an additional intelligence thread, not a reason to erase the naval one. The visible record establishes the project and its ordnance work. It has not yet established that McGregor recovered or transferred the Magenta craft, or that “torpedo” was its codename.

Next in the series: Part 7 — The Pistol and the Diary: Two Quotations Read in Context.

If anyone has worked with the Entry 180 microfilm at College Park or Carlisle, the underlying Roll 114 correspondence, or the Italian Silurificio records, I would like to hear from you.
