It's the original keyslip but you gave me an excellent ides with veneer.

Somebody broke the original key slip. Obviously the keyslip has to be higher
than the thickness of the keyframe + punchings + dip. using the available
punchings when the piano was made. Glue a strip of veneer to the bottom of
the keyslip
