This is in bad shape. It was cut up for an aftermarket joystick.
Update: Removed all buttons and Joysticks. Joystick cleaned and rebuilt. Stripping the old overlay and glue with a citrus stripper. New CPO from This Old Game has arrived.
I'm going to CAD design a new panel. This one is too far gone, and welding on it to fix it just made it worse (warped).
