'Cabaret' was the first machine from this manufacturer to feature a round up-post between the flippers. Chicago Coin was already producing games with this feature as early as April of 1968. The first instance of the round up-post is found on Rally's 1967 'Play boy'. Interestingly, this device was patented by Williams: Patent 3,578,802 [VERTICALLY ADJUSTABLE BUMPER FOR BALL ROLLING GAMES] filed February 25, 1969. Granted May 18, 1971 to Frank T. Murphy, Norman R. Clark, and William E. Casey. Assignee is Williams Electronic Manufacturing Corporation. The manufacturer's flyer places emphasis on the appearance of the up-post feature for this game. We have two promotional photos from them. One shows an up-post and one does not. Shown in this listing are two Sample games that do not have the up-post. The game with images attributed to Bisschoff is located in South Africa and has no serial number stamped on the cabinet or appearing anywhere else. The round holes drilled in the playfield near each flipper likely were done by an operator to convert this game to the longer 3-inch flippers. The game with images attributed to Lust is located in Germany and its backbox is tagged with serial number 9471 and its lower cabinet is stamped and tagged with serial number 9473.
