Douglas   1920   2 ¾ HP   Model WD  2 speed   348 cc  SV  flat twin   frame & engine # 46205

This Bristol-based firm developed the horizontally opposed fore-aft unit in about 1907 and continued utilizing this engine layout  well into the thirties. 
The earliest Douglas models had direct belt drive, but in 1910 a two-speed gearbox was added, with the control on top of the petrol tank. Douglas machines became very popular because of their lightness, ease of starting and speed: in the 1912 Junior TT races Douglas took first, second and fourth places. 
In the First World War  thousands of  2 ¾ HP machines were commissioned for use by despatch riders and  performed splendidly; the first years after the war only detail changes were made, a notable change for the 1920 season being a new frame layout  to accommodate for wider mudguards and to give greater wheel clearance. 
Attention to front fork design had resulted in an improved method of adjustment and lubrication and a stronger construction.
1920 was also the first year that the petrol tank had rounded edges.
This Douglas has been carefully restored a number of years ago.
