Here's a 50's Bingo on FleaBay.

This is a VERY nice example of an original Bally Bingo. The only unoriginal part is the Bally/Williams legs, which will buckle under the weight of the machine if it is dragged across the floor. The asking price is a little too high for a non working game, but to find one in this condition (working or not) is almost impossible !
