Quoted from DennisDodel:

57 years in Nebraska and Minnesota weather. What condition will it be in? Most likely the backglass is shot. What else might have happened to the game during that time? Playfield splits? Rusty metal parts? Certainly gummed up, hard motor grease. Dried out leather clutches? What else? There does not appear to have been any water damage to the box. No rodent or insect damage present.
Hoping to end speculation over a few things that have come up over the years regarding new bingos.
Things that I have been told by old operators that have been disputed by some bingo enthusiasts over the years.
1. Bingo paperwork was not included with the games and had to be ordered through the distributor or directly from the factory. Most of us think the paperwork came with the game. I agree with this.
2. Reinforced bingo legs came from the factory that way. Some bingo guys dispute this. I'm 99% sure they came reinforced.
3. Bally shipped their bingos with 'Dead' rubber on the four red playfield posts. Some dispute this and think that dead rubber was added by "greedy" operators. I'm saying that this game will have factory dead rubber installed. (Probably ALL of the rubber is dead by now, but original Bally dead rubber is a grey color and should be easy to identify.)
Anyone have any other questions about this era of game?
I will probably take the game to the fall York show and open the box there. There is a bingo row set up there every year where Nick Baldridge brings his Multi-Bingo and others bring bingos to play. There is also a chance that I will open it at the next Houston show where Shawn Farwell is hoping to unveil his acrylic see-through Golden Gate bingo.
Thanks for playing along.
Not sure what we will find but it will be fun opening the box for all to see.
