This is a single model sales catalogue for the OC Douglas. The OC is a 600cc OHV opposed twin cylinder motorcycle advertised by Douglas as The Ideal OHV Dual Purpose Mount. It would have been a top of the range motorcycle for the Bristol manufacturers and was sold as the OC Sports, the OC Solo, the OC Sports Combination and the OC Touring Combination. An attractive feature of the Douglas models from 1926 onwards was the servo internal expanding band brakes. This model had 8” brakes front and rear which were a great improvement over other manufacturers fitment of 4” and 5” brakes.
