The manufacturer produced the backglasses in both crystal glass and Plexiglas. 'Alligator' is the German model of Bally's 1969 'Gator'. The US game 'Gator' has schematic part number W-1042-64a and the German game 'Alligator' has schematic part number W-1042-65a. According to Christian Jacobs, a collector in Germany, an employee of the major German importer L�wen-Automaten told him that the name 'Alligator' was chosen because the words 'Bally Gator' on the backglass would have sounded strange to German players of the time, when the English language was not ubiquitous in Germany as it is today. Price to Operator: 4850 DM (per 1969 price list from Lowen-Automaten, Germany)
