Hello friends,  Another new project is rolling through our workshops.
It is a late '20's vacuum piano for a large Wurlitzer organ.  The valves
on the stack control 4 pneumatics each and are made of pot metal.

At this stage in the game the valves are tight and work quite well;
however, since pot metal is cursed with its own eminent self destruction,
I wonder if there were enough of this style of valve that someone may be
making new replacements?  Does anyone have a suggestion?  Or a source?

Thanks all.
