Registration no. not registered
Frame no. none visible
Engine no. ZM33.4032.

This handsome Historic racing 'special' appears to consist of a BSA ZM33 499cc engine dating from circa 1950 in a later BSA duplex swinging-arm frame. However, it should be noted that the primary drive cover has a riveted-on plate, required for historic/classic racing, showing engine dimensions of 71x88mm bore/stroke, meaning that the unit is in fact a '350' (the engine crankcases and crankshaft assemblies are basically the same for both engine capacities). Other notable features include an Amal GP carburettor, alloy wheel rims, alloy engine plates, Koni shock absorbers, Smiths Chronometric 8,000rpm rev counter, megaphone silencer, and a large ducted and vented front brake. There is no racing history with the machine and it is not known when it was acquired or last used. Careful recommissioning, or possibly more extensive restoration, will be required before it is fit to return to the racetrack and thus the machine is sold strictly as viewed. There are no documents of any kind with this Lot.
