Were there generally 5 gears that came with the game numbered 1 to 5, with the 1 being the most liberal? If so, I may be looking to buy 20 #1 gears.
Quoted from bingopodcast:They did! There were several gears that came with the games, and the operator could select. The photo shows that this operator was particularly tight because they used the #5 gear, which has the lowest reduction ratio (IIRC). #3 is more fair to the player.
