Upon furthur inspection, the Parts list for AH 100 6 index lists the following: vehicle types, detail index, part # index, engine, clutch,electrical, gearbox and overdrive, prop shaft, rear axle and brakes, steering, front suspension and brakes, brake pipes, rear suspension. chassis frame, controls, petrol tan,, radiator, road wheels, tools, aand body index. I cannot find any publish date, but I did find that the vehicle date refers to BN 4 from June 56 and BN 4 L , May 56. It has red/orange cover, loose leaf pages, with Austin Motor co., Longbridge, Birmingham. Any other ideas. Thanks, Cliff
