and Glasgow to enlarge their spares and repairs network. Dennis and Duple had developed the Dart, a midibus bought by London Transport as a one-man operated bus to replace their AEC Routemasters. At the end of 1989 Dart bodywork production moved from the closed Duple to Carlyle Works in Birmingham. The Dart was followed by the Lance which used independent front suspension to allow a low floor halfway down the vehicle. The next year Guildford factory moved to Slyfield Industrial Estate and into new premises allowing room to increase production. The work force was more than 300. Shelvoke's design rights were bought from the receiver in September 1991 and their parts and service depots at Merthyr Tydfil and Birmingham were taken over. Dennis now had 27 service outlets. Carmichael Fire, a rival manufacturer of a range extending from Land Rover based fire tenders up to 8 x 8 airfield crash tenders, was rescued from its parent's receiver in 1992. As intended Trinity Holdings was successfully floated in 1992. At that time it was described as a group of famous motor engineering names including Dennis fire engines, buses and dustcarts, Duple bus kits and Reliance Mercury airport tenders. Trinity claimed it was Europe's largest specialist vehicle producer making specialised products for niche markets. Dennis held 40 per cent of the British fire engine market, the Dart mid-sized bus was Britain's biggest seller. In 1993, Trinity entered a joint venture with UMW in Malaysia to build buses in Malaysia from Guildford built chassis kits and Duple Metsec body kits. Trinity withdrew from the venture in 1998. In December 1995, Trinity purchased the aircraft and cargo handling division of ML Holdings: Douglas Equipment and Schopf. In October 1997 Trinity rebranded itself as the Dennis Group. It also revealed an order from Stagecoach Group for 100 Dennis Dart double-decker buses. In the first half of 1997, it produced made more than 1,000 buses and fire engines, restructured the assembly plant at Warwick and expanded its Guildford plant increasing capacity 25 per cent. Low-floor bus chassis Henlys Group, the new name for Plaxton, made buses which it often mounted on Dennis chassis. For some years they had together made double-deckers for Hong Kong and British Columbia and mini-buses for English customers. The Dennis and Henlys combined production held 40 per cent of the British market. Combined along with third partner Volvo they held the biggest
