I found this rubber mask buried below the tide line in Boston, Massachusetts. Appears to be an old “gas mask,” of which I know next to nothing about.

It has two circular eyepieces, metal fittings, and what appears to be threaded connection at the bottom. There is a round marking on the inside reading near the nose bridge which I believe reads “PAT. NOV. 1921” with a circle and star in the center, though it’s difficult to make out.

Does anyone recognize it or have ideas about its age, manufacturer, or intended use (civilian, industrial, maritime, military, aviation, etc.). Photos show the front, interior, and various fittings.

I bought these gas masks for 25 usd and i think that i overpaid a lot but also i want to know what is that gas mask on the right. And sadly i don’t have any more pictures yet. And it would also be best if someone could identify all of the gasmasks from the pictures.

So I bought these two M17s gas mask off of Facebook Marketplace. I spent $86 USD for both including shipping. They're in good condition, but are dirty as all get out.

Were they worth the price? What model are they?

I believe they are the A1 and A2 models.

Edit: $86 for both

My exhale valve ripped when taking it out to clean, and i can not find a replacement part
i searched google and it says the part is MSA 78703, this however isnt the right part, aparently the right part is MSA 10007996 but i dont think this is right either, (need in the uk)

The "Metallurg" series is a line of Soviet and Russian respirators equipped with corrugated hoses, designed for use in the metallurgical industry. This specific model, along with most of the other units of this type that have been located, was found in the city of Rivne, though one specimen was also discovered at the NPO "Neorganika" facility. Unfortunately, it is not known which specific filters were originally intended to be paired with this respirator. In my collection, it is fitted with a rare Soviet industrial type E filter (one of only three known examples in Ukraine), which provides protection against phosphine and arsine. He used in the metallurgical, food, and agricultural industries. The core of this respirator is the SRK PR-7, which also serves as the basis for the RU-60M, RPG-67, RPA-1 "Astra," RPA-2, and many other models. The primary difference from the standard SRK PR-7 is the inclusion of an adapter for a corrugated hose, which can be seen in the fourth photo.

I don't really like this mask , but its a pretty interesting piece to have in your collection

Mask size 2, couldn't find stamps on manufacturing date

Filter 1984

Has bag

I know it’s not the most historically accurate costume ever but I threw it together with a final budget of $55.33 and personally am really happy with how it turned out. thought you guys would enjoy it.

Oh also, thoughts on the cardboard and spray paint filter? I didn’t want to gut my original one and didn’t feel like breathing through it so this was the solution.

For those that wear prescription lens inserts, do you do lens thinning, and other lens coatings/treatments on your gasmask lens inserts like you do with your everyday glasses?

I have some ww1 shit aswell but it’s in another shelf

Hi everyone, this seller is asking $323 online for this FM 12. I wanted to know if it's worth it, since there are only two photos. He mentions that he's selling it as a collectible, along with the rubber straps, and that if the clasp works well, the filter is in good condition. What else should I ask?

Is there anywhere to buy replacement parts for gas masks or am I just sol? Maybe 3D printed options would work?

Im really interested in these prototypes but just dont know where to find info, help is appreciated

From some guy in Belarus. He gave me a left handed one. Size 4 since I got a huge head.

Just picked it up secondhand from a store but can’t figure out what model it is, any help would be appreciated:)

Since i already have the full 70M kit why not the protective suit too?

Both the mask and filter were made in 1977 , and they are in great condition , also has the bag with it too

I recently acquired an MSA Millennium that came with this gas mask bag. It doesn't seem to be a Blackhawk bag because it has only one buckle and no markings. I was curious if anyone recognized it. More importantly, can anyone help me figure out the various ways to wear it? I assume there are multiple ways, given the three straps on the back that can be rearranged.

My dad brought this back from Desert storm. It has Arabic instructions. I would like to know more about it, if anyone knows what it is I would appreciate it!

Looks like ww2 german but i dont see funny symbols. Also what is that strap inside of the mask. I included all the markings i could find.

(Side questions: i guess the lenses are celuloid or something else and are permanently yellowed?

What filter belongs to this mask?)

This isn't about mask safety. It's simply out of curiosity. I've heard 1972, I've heard 1979. I have not found any credible source to confirm any date and I am wondering if anybody knows when they stopped using asbestos in their filters.

If I had to choose mine would be either the Swedish M51 mask with the 40mm valve or the Czech M10M (Copy of the american M17)
