c.1929 OK-Supreme 350cc Project
Engine no. 3843
OK - the ‘Supreme’ came later - was founded by bicycle manufacturer Humphries & Dawes, of Birmingham. The company experimented with powered two-wheelers in the 20th Century’s early years before exhibiting a Precision-engined range in 1911. When Charles Dawes and Ernie Humphries split in 1926, the latter continued motorcycle production using the name ‘OK-Supreme’. The firm first entered the Isle of Man TT in 1912, but had to wait for its finest hour until 1928, when OK-Supremes filled four of the top six positions in the Lightweight race, Frank Longman scoring the marque’s solitary TT victory. Offered for restoration, this ‘barn find’ OK-Supreme is fitted with one of Granville Bradshaw’s overhead-valve, oil-cooled engines, a design used by various makes and commonly referred to as the ‘oil boiler’. The machine was purchased as a restoration project from a private collection in 1971 and has been on display in the Museum since its opening.
