Nice find...Can you post some pictures?

I use these type of three wheel skates once I have the machine together and need to work on it for any period of time. It is easy to turn and move the game with these skates.

You might want to spend a few dollars extra and get the heavy duty type or the cheap ones will not last but a few minutes since a bingo is a heavy pinball machine.

Nice looking High Flyer in great condition and a sweet six card player with the 4 corners, super lines, red diagonals and double or nothing features. The EM six card players are my favorite bingos. They have a quick coin deposit and max limit which in turn makes for more playing time to try to score some in line wins, replays or free credits....

Bally really stepped up in the 1970's with their six card bingo pinball machines. Too bad your game wasn't in a High Flyer cabinet with the planes on it. I always liked the Wall Street cabinet design to though which I think is supposed to be the New York skyline. Nice game and great player! Thanks for sharing.
