Antique Musical Instruments/Pistons for a Besson tuba 2-20

Question
Hello Kenton,

I have a Besson tuba 2-20 (serial #458292,years 40's/50's) which the first piston has been seriously dammaged. Do you have an idea of a source where I can find  such a piston?

Thanks for answering.

Regards.

Bob

Answer
Well, there are about three approaches.  

First, you say that it is seriously damaged.  Yet, it is probably your best bet to see if it is not possible to repair the original.  Sometime some pretty serious damage can be rebuilt.

The second choice is to find another tuba and use it's parts.  And, it probably will be easier, cheaper and faster to simply replace the whole valve assembly with the valves from the parts horn.  It might be possible to fit the piston, but it is still going to have to be rebuilt and lapped in.

The third choice is to have a competent repair person remake the valve from scratch.  That is a difficult project and not cheap.

Please note: My area is BRASS instruments, not other wind, string or percussion instruments. I will provide information on antique, obscure and out of production BRASS instruments. 1) Please don't ask for evaluations, I'll not provide them on this site. 2) I am often asked very similar questions, so I'd invite you to first check on Horn-u-Copia.net. Much of the information I have garnered about this topic, I have posted on this WEB site.

I perform in several historical bands, have informally researched the area, repair brass instruments, and operate a Forum dedicated to the topic at http://horn-u-copia.net
