Lot 358: 1929 Sunbeam 347cc Model 5
Already established as makers of high-quality bicycles, the firm of John Marston Ltd, of Wolverhampton, introduced the first Sunbeam motorcycle, a 350cc sidevalve single, in 1912. The marque quickly established a reputation for sporting prowess, achieving second place in the 1914 Isle of Man Senior T.T. and winning the 1920 race. Overhead-valve engines were introduced in the mid-1920s, but early successes were achieved with sidevalve-engined machines. This Model 5 sidevalve dates from 1929, the first year of the ‘saddle tank’ Sunbeams, and was previously attached to the Watsonian launch-type sports sidecar (Lot ???). Offered for restoration, the machine comes with old-style continuation logbook and Department of Transport letter linking the registration mark ‘PG 1129’ to the machine.
