Lot 621: 1925 Triumph 494cc Model P & Triumph Sidecar

Collectors' Motor Cars, Bonhams (10 September 2005)

A landmark machine in the development of the motorcycle in Britain, Triumph’s Model P debuted at the 1924 Motor Cycle Show. A no-frills sidevalve-engined model, the newcomer was priced at £42 17s 6d, at which level it undercut every other 500cc machine then on sale in the UK. Production was soon running at an astonishing 1,000 machines per week, the Model P’s outstanding success undoubtedly hastening the demise of many a minor manufacturer. Production continued until the decade’s end, by which time the Model P had spawned a plethora of derivatives and lost penny-pinching features such as guide-less valves and bicycle-type front brake. Unusual in retaining its original Triumph ‘Gloria’ sidecar, this Model P combination was first registered in Derbyshire. One of the earliest of Eric Houseley’s acquisitions, it was restored after purchase and has been in the Collection for 40-plus years. The machine is offered with Swansea V5.
