Hohner Electra-Piano T repair

[crosswick]

Hello! I'm in the process of getting a Hohner Electra-Piano T to work properly for a customer. I thought I'd share some info on it here, also to get some suggestions perhaps; mainly on what materials to use for the dampers! Originally it looks like the reeds were dampened by some kind of clay pieces - or at least it has turned to clay.

Has anyone found a good replacement material for these dampers in terms of sound and durability?

The other thing that seems to need replacement is the little foam cushions that the hammer assemblies land on; these have become brittle.

Here are some pictures:









A lot of the damper blocks had already fallen off; I took all of them off except the lowest
