Score reels by maker

Up to the 1960s makers shared much the same reel mechanism. Gottlieb and Williams reels are aluminum with printed numbers, Genco used aluminum with a paper number band, and Chicago Coin used plastic. Midway from 1965 to 1975 used motor-driven reels instead. Some reels carry a circuit board for match and high-score sensing.
