Those are valves used in a Wurlitzer home model player.  When they
are rusty with the threads messed up I make new valves.

I punch new fiber pieces.  I use PEM fasteners for the metal stem.
These are fasteners that press-fit into a hole in the fibre like
originals.

Look on MMD website for making new Wurlitzer valves.  You need to
apply shellac around the lower seats.
