1913 - 1914
The W.W. (Winter of Wandsworth) was a light car which used an 8hp V-twin Precision engine, with Charter-Lea gearbox and shaft drive to an overhead worm rear axle. For 1914 they changed the specificiation towards the cyclecar theme, with a V-twin Blumfield engine, friction transmission and belt final drive. This model was known as the Winter rather than the W.W.
