Here is a Nitro Ground Shaker by Bally from 1980. Unfortunately the cabinet was painted. The playfield was peeling paint and very dried out. As usual with these old pins we had to work on almost every area to bring it back to specs.. We spruced it up with new pop bumper caps and new targets. Also new white nylon acorn nuts help a little. Had to plastic weld and mylar tape the upper left plastic - it had a pile of epoxy on it when delivered. The backglass is perfect! The invoice notes follow:
