Two thoughts come to mind. The back of the key end felt is rubbing against one of its
neighbors' damper levers or the front of the key is rubbing against the key slip. I've
found both. In the latter case, and with one particular piano, it only happened when the
owner played. I couldn't get it to duplicate. Turned out, the owner was a VERY heavy man.

Oh, yes. One other thought. I've also found that on some of the S&S keyboards made by
Pratt-Read and/or Pratt-Win the front rail pins were occasionally bent to one side or the
other (for even key front spacing with the keys at rest) so much that when certain keys
approached the bottom of their travel they would rub against their neighbors.
