Hi all,  A friend of mine is rebuilding the stack on a 1928 Duo-Art
grand piano.  He has found that he will be needing the fiber retaining
rings for the stack valves.  Player Piano Parts Inc. no longer has
a supply of these rings [formerly sold by PPCo].

Does anyone have a set of these rings for sale or know anyone who
is making them any more?  Thanks very much for your assistance!

Best wishes for a great New Year.

Mike Walter
