I'm missing the 2nd valve piston and assembly.

I have no idea. I've never really had to replace any instrument parts before.

I got my hands on an old Conn 15J tuba that needs a bit of work and at least 1 replacement for a missing valve piston. Seller kind of pulled a fast one on me and now I'm stuck with this thing. I'm at a loss as to where to find/purchase this and I've searched heavily online. I don't really do any ...

I got my hands on an old one missing a valve piston. Anyone know where I could purchase a replacement?
