Gottlieb rat trap and decagon score reels
1970s reels have their nine and zero switches on the outside where they are easy to reach. Older Gottlieb rat trap reels with a circuit board must be partly stripped to reach the switches under the board. From 1967 Gottlieb's ten-sided decagon reels give easy access even with the board fitted.
