Thank you, everybody, who helped me find a solution. Yes, it were much too long leg bolts that had been screwed into the action through the key bed all the way back. The front leg bolts were good, the hind leg bolts were the culprits. Incidentally, this also threw the action out of alignment. About 30 hammers were hitting the 'neighbors ' strings. By replacing the old long bolts with new shorter bolts, the action went back to normal, thus a lot less work to make the piano play again.
