100 new cork gaskets for Gulbransen player piano 4 tier (deck) unit pneumatics.  Not for the 3 tier glued or unit pneumatic stack.  1/16" thick, laser cut, very precise.  As with all my ProFit gaskets, these were measured and made using factory original parts, not copied from a copy.

1 and 10 packs available in my eBay store if you don't need 100.  Many more Gulbransen and other manufacturers parts also available.
