Hello All, been a long long time. As we all know the Bb-103 is a unique little horn. Valve block feeds from bottom instead of 1st valve, pistons are interchangeable. I don’t know of any other tubas that share these 2 traits alone. There were 2 different serial # sets I believe. I’ve heard they were different bore sizes also. The curved dogleg was supposedly .610 while the Z shaped dogleg version was .661, even though the bore through the valves was the same for both, supposedly. I always thought a .710 rotor where the tubing exits the 1st valve would be a great place for a step valve, thumb actuated. I literally had a near-perfect horn fall into my lap. Appears to have never been dicked with. What price can I assign to this?
