Grand Slam Machine

Here's an overall shot of the game.
the cabinet has been repainted, so it will need to be stripped and restored to original factory design.
Overall, though, the game looks to be in pretty good shape.

Grand Slam Backbox

The backbox contains the popular Williams 'Running man Unit' mechanical action of players popping up and running the bases. Needs cleaning and one leg repaired on one character, but otherwise is complete.

Grand Slam Playfield

The playfield shows a little bit of wear, but should clean up nicely with a little touch-up and cleaning.
