1955/48 BSA 500cc B31/A7 Scrambler Project
Frame no. CB31 11637
Engine no. YA7 4942
The incomplete BSA-based moto-cross 'special' offered here consists of the frame from a 1955 B31 350cc single and a 1948 A7 twin-cylinder motor, the latter featuring the early 'semi-unit' type of engine/transmission construction, while the front forks are Norton Roadholder. Period photographs (scans of which are available) taken of this competition machine in the early days of the Parker family's ownership show it with the same competitor number on the side roundels. There are no documents with this Lot, which is offered for restoration and sold strictly as viewed. No reserve.
