OP, if you were local, I'd fix it for you but shipping back and forth alone costs 10x more than what the piece is worth. @B Flat may be able to help you but quite honestly, even local postage may exceed the value of the piece.

Just I guess, but I'd guess that someone sanded/ground it down in an extreme attempt to open it, sanded into the window giving it that irregular shape, and also sanded off the original tip rail.

No, nobody would do anything like that.

Much more likely is that whoever played the MPC got in a bar fight with the piano player and the piece accidentally fell off and got stuck between the pedals and stayed there unnoticed for 2 decades. And when the bar closed and they moved the piano, it scraped on the floor, hit a few nails and eventually fell off, just when the cleaning woman came with the big shop vac, so it got another few tumbles. There is really no other explanation!
