During a period in the 1960s, Gottlieb shipped pinball games to Europe with plastic (Plexiglas) backglasses in them. They stopped this practice when it was learned that players would cheat by drilling a hole in the plastic near the replay mechanism. Some 'Sunset' pinball machines have these plastic backglasses. One image shown here has a small hole in the replay window area. Several examples of this game have been reported to us as missing the light socket and wiring on the backbox insert which would have illuminated the red buffalo silkscreened under the first-player score, the apparent target of the rifleman on horseback. The reason for this omission was that the manufacturer placed the replay adjustment score plug assembly to block the hole where the lamp would go. We have two images which show this, from the game with serial number 05530. We do not know if all 'Sunset' games had this issue.
