This machine is in for a complete overhaul. It's one of the greasiest, dirtiest, and most sticky units I’ve encountered in some time, with stubborn, dried-on tacky grease coating every surface.
FYI: I'm told that this machine is/was the very first machine at the Tropicana Casino in Las Vegas and then was moved into the Tropicana Showcase when new machines came in. It's now in a private collection.
Update: This machine came in not working. Found that it was full of old dried grease everywhere. This went through a full overhaul with every nut, bolt, washer, and cotter pin removed and cleaned. Polished chrome as best as I could. Tested, works, and pays out as it should.
