[1] Before World War I Richardsons had made children's toys and scooters and were pioneer makers of model aircraft.
With peace it was decided to branch out into cyclecar manufacture and a car was designed by Albert Clarke, the brother-in-law of Charles Richardson.
Both power units drove through a friction drive and belt to the rear axle.
Early cars had an acutely sloped dummy radiator, but this changed to a more stylish vertical design in 1921.
It is thought that around 500 cars were made before production stopped in 1921.
