During World War I Alfred Angas Scott had made sidecar machine gun carriers.
The layout was mostly derived from a motorcycle-and-sidecar combination, but wheel steering was accomplished by rack and pinion.
It used a water-cooled 578 cc twin-cylinder two-stroke engine supplied by the Scott Motorcycle Company.
Power was transmitted through a three-speed gearbox to the offside rear wheel by shaft.
[1] The vehicle was intended for military use, but orders failed to come, so Scott converted it to civilian use and announced it in 1916 as the Sociable.
