BSA's rugged, workaday B31 was manufactured from 1945 to the end of 1959, its overhead-valve engine providing the basis for the renowned Gold Star sports roadster. At the time of its introduction, the B31 was BSA's sole all-new model, joining the lightweight 'C' and heavyweight 'M' ranges carried over from pre-war days, and was produced initially with rigid frame and telescopic front fork. In January 1946 it was joined by a Competition variant, the B32, which boasted a high-level exhaust system, 21" front wheel, additional chromium plating, a crankcase shield and lowered gearing. An alloy cylinder barrel and head, broadly similar to those used on the contemporary Gold Star but retaining a separate pushrod tunnel, became available as B32 options from 1949 onwards, as did plunger rear suspension in common with the rest of the 'B' singles range.
This early B32 Competition Model was despatched from the factory to Copes of Dudley on 8th June 1949. An accompanying BSA Owners' Club letter notes that the engine (fitted with the Gold Star-type alloy top end) is not original to the frame and that the serial number appears to have been re-stamped, concluding that the machine appears to be 'modified but to original spec'. 'JFD 843' was restored to a high standard in 2005 and has been dry stored since completion. The machine is offered with the aforementioned BSAOC letter, DVLA and Dudley Council correspondence, old-style continuation logbook and Swansea V5C documents.
