I am reluctantly selling my 3V Bb frankentuba. The term frankentuba means that it is made from different tubas. The main body is a 1922 Boosey and Co Bb tuba, the valves are from an Olds 099 and the leadpipe is from a Miraphone 1290. This is a great tuba and plays very well. I was thinking of adding a 4th rotary valve. I do have all the original valves and pipework. Please message me for photos as I can't seem to upload them.
