I recently purchased a 1981 Bally Medusa pinball machine for $165.

Updated:

The flipper is now working after winding my own coil (thanks to the poster who mentioned it elsewhere). I still need to remove the center playfield display and clean it. It's partially lit. I imagine the rubber zebra strip connector between the pcb and display panel is dirty.

The only other thing broken is the ball post bumper between the flippers (The one that gives you five "shots" per game to save your ball). I have the piece and can reglue it but I might just try to find a rubber foot to push over the remaining part.

I can post pics if anyone would like to see it. All the lights are working but I'm about out of spares I found inside and looking for more.

Update:

Thanks Billy Mays (RIP) .. I used the easy putty to re-attach the bumper between the flippers. It dried in an hour and is super solid. It worked better than epoxy and I didn't have to worry about anything oozing downward.

Can someone tell me where to find the serial number please ???

I noticed the backglass artwork has the nipple bumps and the unintentional crease between her legs. It is signed by Kevin O'Connor... I'd like to know the rarity.. TIA.
