During those 20 years in that barn, It has been through TS Alison, couple hurricanes, Then the lifetime storm Harvey couple years ago. She survived them all. I currently have the magazine selector and player mechanism tore down and DEEP cleaning it. Down to wire wheeling the screw threads and C clips. I have a video of the motor and tone arm playing a 45 that came with her.

The corrosion and filth is incredible. White chunks on the power cables and wire harness covers, spackle everywhere, Mickey mouse got trapped where the cash box once was and came to his surmise, rust, dirt, mold, everything. Stripping the cabinet and then pressure washing it. I need to take more pictures or video but not used to it.
