Sunbeam introduced overhead-valve engines in the mid-1920s having established its not inconsiderable sporting credentials with sidevalve machines. The Wolverhampton concern missed the virtually wholesale switchover from flat-tank to saddle-tank frames for the 1928 season, and its saddle-tank models did not appear until September of that year. Changes to the ohv engine were confined mainly to its top-end. Early flat-tankers featured a straight-ahead exhaust port, a peculiarity which necessitated the adoption of a bifurcated down-tube, then later in the 1920s the fashionable twin-port cylinder head became an option before Sunbeam standardised a single-port design in 1934. Pushrod enclosure had arrived by 1930 to be followed a couple of years later by partial enclosure of the rocker gear. Introduced in the autumn of 1930, the all-new Model 10 featured an overhead-valve twin-port engine incorporating an in-sump oil reservoir, while its conventional cycle parts were lighter than hitherto. Although something of a departure from traditional practice, for the first time there was no fully enclosed chaincase on a Sunbeam roadster, the Model 10 was a capable performer of exceptional frugality, over 100mph being achievable. The Model 10 was produced for only two years before Sunbeam reverted to the old Model 8. Restored to a high standard and kept in storage, this very rare Sunbeam remains in good order and should require only the minimum of re-commissioning before returning to the road.
