The first motorcycles made by the Birmingham Small Arms Company in the early 1900s used proprietary engines such as the Belgian Minerva, and it was not until 1910 that the firm introduced a BSA designed and built machine. The first model to feature the marque's distinctive green and cream tank colours was a 499cc (3.5hp) side-valve single, which was soon complemented by a 557cc (4.25hp) long-stroke version, built initially with single-speed belt drive transmission and later on with a three-speed countershaft gearbox in the case of the Model K, to which the Model H added chain final drive. The present owner purchased this Model K as a 'basket case' in 1998, and over the succeeding couple of years treated the machine to a complete 'last nut and bolt' restoration. The paintwork has been stove enamelled, the wheels completely rebuilt and the magneto re-wound. The engine has a new Alpha big-end, piston rings, valves, valve guides and springs, while the transmission has a new primary drive chain and rear drive belt. Although the machine has been re-commissioned, it has not been ridden extensively and still requires running in. Finished in BSA green with black cycle parts, it is offered with old-style continuation logbook, road fund licence/MoT to May 2004 and Swansea V5.
