Lot 220: Douglas Model G31
From the Ivor Halbert collection. Douglas began making motorcycles in Bristol in 1907, quickly developing a horizontally-opposed twin-cylinder engine placed lengthways in the frame which became a signature of the firm. Douglas became a major supplier during World War One, producing over 70,000 bikes for the military. After the war they became best known for speedway bikes, dominating the sport throughout Europe during the late 1920s. In 1933 a Douglas Model T6 famously became the first motorized vehicle to circumnavigate the globe, ridden by Robert Edison Fulton.
Dating from late 1930, this particular machine is believed to be a very rare Douglas Model G31 with a 600cc overhead valve twin-cylinder horizontally-opposed engine and dry sump lubrication. Transmission is via a three-speed hand-change gearbox. According to a letter in the history file, the London Douglas Motorcycle Club believe that only one other G31 is known to the club and "possibly no more than half-a-dozen of these machines would likely still be in existence worldwide." Believed to be in good running order but not ridden for several years, the bike comes with a modern V5C and a small quantity of spares.
