Does anyone have parts 65-3150 + 65-3117 + 65-3153 + 24-4246 + 65-3129 to cover BSA Service Sheet Number 64 to modify the 4 speed B18 1937 250CC Hand Operation Gear Box or a replacement gearbox ?
regards James
James, the B18 is a 1936 model and has an entirely different gearbox. What is the matter with yours? Regards, Leon
