Just to share my newest acquisition with you ...
Have just bought a used Gronitz F/Bb double tuba. It's in good condition and all the valves and slides are working fine. It seems to be made of gold brass, has only a few little dents and lacquer is ok.
It has 4 “normal” step valves, one “long” halftone after the 4th valve to reach the B, operated on the back, and then two valves operated together with the left hand do go down a quint to the low Bb.
Seems to be a fine horn but I have no experience in playing F tubas. Will either learn it or sell the horn later on?
Here a few pics:

Re: Gronitz F/Bb Double Tuba
I actually tried out a tuba like that at a little brass shop in Hamburg back in 1963. The Bb valve routed the air through the F tubing and then through additional loops to provide the extra length needed for Bb valve tubing. (It was more like a compensating valve system, rather than a true double horn.) The resulting Bb tuba was so stuffy that it was almost unplayable. I don't know if this one is the same design.
