I just noticed how the lead pipe does not go straight into the first valve like many other piston tubas. Perhaps that’s why the valves are so good!! (No sticky first)

I’ve always had the suspicion that this horn is a rare case of a CC turned into a BBb successfully.
Looking closely, there’s about one foot of tubing wrapped up in that extra bit before the valve set. And then the main tuning slide is extended (it appears) about 3” on either side. Somewhere else is about another 6” of added bugle.

That could be...or rotary B-flat into piston B-flat, with very little else altered...(??)
Yeah...
I think the baseline was a PT-3 or PT-20 from photos, but I am just guessing.
I wouldn’t be surprised, and wondered the same thing. This B-flat is easier for me (personally) to keep well between the intonation ditches than those C models...
...which makes me wonder if some of the wonkier tubas in C need more mouthpipe and less expanding bugle...which seems to be the opposite of the tendency when designing them, doesn’t it?
