After victory in the 1920 Junior TT, AJS’s new overhead-valve 350 racer scored a memorable double the following year, Tom Sheard winning the Junior race, and Howard Davies the Senior - the first time such a feat had been achieved on a 350. The production version made its debut in November 1922, delighting clubmen everywhere with its ‘racer on the road’ performance. A right-first-time design destined to achieve countless successes in the hands of privateers, the overhead-valve 350 AJS - latterly known as the ‘Big Port’ - changed only in detail before being superseded by a much-revised M6 model for 1929. The latter’s engine incorporated a number of improvements including enclosed rocker gear and dry-sump lubrication, while the frame was redesigned to accommodate a saddle tank, and Webb forks replaced the earlier Druids. This twin-port M6 was purchased for the Ehn Collection in 1971. The engine was overhauled and a partial restoration undertaken, the exhaust pipes and their installation being among items as yet unfinished.
