PT-3/3097 History and Sharp Third Partial Mod

[joh_tuba]

Perusing the archives this very interesting nugget popped up.

I've found NO other info but would love to learn more. Anyone have insights they can add?

Hallo Alline,

Your CC tuba is a B&S model PT-3 or in Europe, a 3097. It was likely made in the late 1980s and the 'K' on the receiver is the initial of the gentleman who did the final assembly of your tuba. This model is an interesting mix of BBb and F tuba parts that was extremely popular in the late 70s and 80s in the former GDR, especially in Berlin due to the influence of Dietrich Unkrodt.

I bought a rather tired one a few years back, and in addition to restoring it, I fabricated a new larger leadpipe and modified the body to fix the sharp 3rd partial. It is remarkably loud for a small CC tuba...

Good luck with the sale!
Best regards from Berlin,

Is there a German or European equivalent of Tubenet where I can pose this question?
