In the course of my occasional restoration (hobby) projects of
88-note as well as reproducing pianos, I need to replace cork
gaskets that seem to have started out as dense 1/32-inch pure cork.
I have been unable to locate a source for that thickness.  PPCo
carries this thickness in rubber-filled cork, which I like to
stay away from.

In case this pure cork thickness has gone the way as some other
original stuff, is there a good substitute that I should use?
Would appreciate any help.
