• Interesting BSA hybrid • Present ownership for 35 years • An older restoration 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. Acquired by its late owner in 1982, the interesting BSA 'special' offered here combines the frame of a 1952 499cc ZB Gold Star with the alloy engine of a B32 Competition model dating from 1950. The BSA despatch notes show that frame number 'ZB32S 3627' originally formed part of a ZB34 Gold Star listed as '2nd hand ISDT', possibly indicating that it had been used in competition. Issued in 1953, the registration mark 'NOH 755' was originally on a 350cc B31 (frame number 'BB31 21620') first registered to the Birmingham Small Arms Co Ltd, Small Heath (see old-style buff logbook on file). The late owner successfully updated the machine's frame status in 1982 (the change of engine had already been recorded) and the numbers on the frame and engine match those listed on the accompanying V5C Registration Certificate. 'NOH 755' also comes with two substantial history folders containing correspondence, invoices, and other material relating to its restoration by the late owner in the 1980s (close inspection recommended). The most recent MoT expired in 2010, as did the tax disc affixed to the machine, and careful re-commissioning is advised before returning this BSA to the road.
