V.F. Cerveny BBb upright (Kaiser-style) tuba, nickel-silver pistons, 16" bell. 3 valve. It plays well. I play it. Valves, slides and pistons are just fine. It was historically restored about 7 years ago when I bought it. A440 or A335, I’m not sadly not sure.
Bore 16mm opening. Mouth piece sits in at roughly 28 mm. See pics for the small patch on the inside of the bell made with appropriate brass. Outside the bell you simply can’t even see the need for a patch. The artisan that restored it was quite talented.
Aligned, playing well. Pistons, values, caps, everything moves well.
Circa 1895-1905
