Lot Details
1956 BSA 646cc A10 Project
Registration no. SVU 72
Frame no. BA7S 19340
Engine no. BA10 14965
Introduced late in 1949, BSA's A10 650cc twin closely followed the basic pattern established by the 500cc A7 while contriving to be almost entirely different in detail. The existing parallel-twin architecture was retained for the new A10, with 360-degree crankshaft and single camshaft at the rear of the cylinder block, as was the four-speed gearbox bolted directly to the crankcase in a form of semi-unitary construction. A conventional separate gearbox was adopted when a swinging-arm frame was introduced in 1954, though the original plunger-suspended model remained in production for a few more years. This late example of the plunger-suspended A10 comes with an old-style continuation logbook issued on 24th May 1966 when it was registered to Harold Parker. Additional documentation consists of an old MoT certificate (expired 1967) and old/current Swansea V5/V5C. Incomplete and partially dismantled, the machine is offered for restoration and sold strictly as viewed. No reserve.
