- Lot Description
"Rollover" Slot Bugs (9). Circa 1950. A set of nine "rollover" slot machine percentage devices ("bugs") in three different styles. These cheat attachments were installed on reels with one "BAR" (typically the third reel) to prevent a jackpot win on the payline. Rather than let the BAR register, the bug, attached to the star wheel, would block the mechanism and force the reel to "rollover" to the next symbol. One set is matched for a Mills Novelty Co. machine (model unknown); others unidentified or generic fitment. Sold for entertainment purposes only.
Largest 3/4".
Condition
Very good.
