as the Vixen). The petrol engines included twin cylinder air-cooled MA2 and AN4 models, and twin cylinder water-cooled MW2 and WN4 models. The AN4 was used in the 1950s by Thomas Green & Son on their Griffin models PRR and PRY motorised rollers. Coventry Victor also produced a flat-four air-cooled petrol engine (the AC4 or 'Neptune'), one use of which was in aircraft pressure test trolleys made by Sir George Godfrey & Partners. Major W.A. Weaver (managing director of the Coventry Victor Motor Co) converted one of these in 1955 for use in a Piper Cub aircraft, naming it the 'Flying Neptune'. Coventry Victor engines were also used in airfield pumping sets and to operate hydraulic ramps such as the Hylo Mk II mobile lifter made by Aviation Traders (Engineering) Ltd in the 1960s. Present day The Coventry Victor Motor Company Ltd was wound up voluntarily in January 1971. A.N. Weaver (Coventry Victor) Ltd. was formed in July 1971 to provide spares and offer a service to maintain existing engines.
