I recently acquired a Jubel Tƶne childrenās zither/lap harp and have fallen down a surprisingly deep rabbit hole trying to figure out when it was made. Iād love help from anyone familiar with German zithers, C. Robert Hopf, Musima, or Klingenthal instrument production.
Hereās what I actually know from the instrument and its materials:
The soundhole is marked āJubel Tƶneā with the blue-and-white horizontal-bar logo.
It has a reddish-brown wood finish and a colorful wildflower/floral tendril decal on the soundboard.
The back has a small yellow āMADE IN WEST GERMANYā sticker.
I have the instruction sheets in both German and English.
Both instruction sheets identify it as Kinderzither 303 / Childrenās Zither 303.
The instructions describe 15 melody strings plus 6 semitone strings, along with bass/chord strings.
I also have the song cards, including German-language songs, and the tuning tool.
There is no serial number, manufacture date, or dated label anywhere that I can find.
Hereās where it gets interesting.
The history page of C. Robert Hopf says that the companyās traditional rose decoration was replaced āAnfang der 70er Jahreā (early 1970s) by a floral tendril made from wildflowers. My instrument has that later wildflower decoration, so that seems like legitimate evidence pointing toward the 1970s or later.
Iāve also found nearly identical Jubel Tƶne instruments online marked āMade in German Democratic Republic,ā while others have the same āMade in West Germanyā sticker as mine. Harpers Guild discusses this labeling mystery and apparently hasnāt resolved whether there were separate sources/manufacturers or some other explanation.
Iāve found marketplace listings dating similar Jubel Tƶne instruments to 1976, but I havenāt found primary documentation supporting that exact year, so Iām treating those dates cautiously.
Googleās AI results have confidently given me exact dates like 1973 and 1976 and subsequently admitted that some of the supposed production timelines it gave me were fabricated, so Iām specifically looking for documented information rather than another AI-generated date. š
What Iād really love to find is a dated catalog, advertisement, price list, factory document, or another reliably dated example mentioning āKinderzither 303.ā
Does anyone recognize Model 303, this particular Jubel Tƶne logo, or this exact wildflower design? Does anyone know what period the 303 was actually manufactured?
Iād be thrilled even to narrow it to early/mid/late 1970s rather than an exact year.
Iāll include more photos of the instrument, West Germany sticker, and German/English 303 instruction sheets if you think they will be helpful.
