Artist Bob Timm told us he did both the backglass and playfield for this game while he was at Ad Posters. He said cabinet art was always done at the cabinet maker and, as far as he knew, none of the game artists had anything to do with it. Pictured here is a cabinet bottom of a game with serial number 1644 showing a "brick wall" design. We do not know how many came from the factory with this "brick bottom". The "brick bottom" shows up on other games made in 1980: Williams' 1980 'Firepower' and Stern's 1980 'Quicksilver'. Reportedly, this game was also manufactured in Australia by Leisure and Allied Industries under license by Stern Electronics Inc. However, Stern's production data does not indicate any knock-down games were made, which is how other Stern games were exported to Australia.
