I'm restoring an Electrova coin operated piano (Jacob Doll player
action) and I'm in need of blotter paper gaskets.  The gaskets are
1-1/2" OD and 1" ID with holes for #3 or #4 screws at 12:00, 3:00,
6:00 and 9:00 (photo attached).  I believe the stock number was 592
in the old PPCo catalog.  If anyone has these gaskets for sale or knows
of a source for them, please email me.  Any assistance is greatly
appreciated!

Thank you.
