The Douglas Engineering Company began life in Bristol in 1882, and the company built its first motorcycle engine in 1905. Douglas specialised in horizontally-opposed twin cylinder machines which they produced throughout the 'teens and Twenties and became famous for their speedway winners. Before the Great Depression undermined the economics of the industry, Douglas expanded their range to include 350, 500 and 600 cc models, then the shaft-drive Endeavour (which was the first Douglas to carry its engine positioned across the frame), and finally the Aero which arrived just before WW2.
During the Second World War Douglas made many stationary engines, and then restarted motorcycle production with the T35, another ohv flat-twin 350 cc, set across a duplex fame with torsion bar rear suspension. Various Sport and Competition offshoots were built in the next few years, including the 90 Plus and 80 Plus, and the standard bike evolved through several incarnations to become the Mark V. The Mark V was built until the introduction of the Dragonfly in 1955.
Douglas found plenty of ingenious methods of solving problems which led to a raft of patents, not only for Radiadraulic leading link forks (1948) and torsion bar rear suspension (1944) but also a butterfly valve carb (1945) and gearbox with final chain drive for transverse twin engines (1947).

OSK was first registered with DVLA on the 18th April 1950 and nothing is known of its early life until Dennis Dale of Herne Bay bought it in July 2011 as a non runner, having last been on the road in 1998 before that. He set about restoring it to the condition you see today and had it on the road on the 1st November 2011. The engine was fully rebuilt with a +060 rebore, the mag/ dyno was rebuilt, a w clutch fitted. The seats were renewed and other ancillaries were refurbished or renewed. In September 2013 he sold it to our vendor
who has used her sparingly and is now selling as he is giving up motorcycling.
Sold with the V5C, tax discs 1992/ 4/ 7/ 8 and 2013, various receipts, paperwork and an original Douglas spares booklet.
