This machine came from the Central Aircraft Co of Kilburn, London, using an engine of American origins from Economic Motors of Eynsford, Kent.
At the Motorcycle Show of 1920, this was said to be the cheapest three-wheeler available. It was very primitive and had twenty-inch wire wheels - two at the front and one at the back. It had a skeletal frame and body with a seat for one person.
The name is said to come from Messrs Cambridge (or possibly F. J. Camm) and Broomfield
The engine was of American origin, but had been taken up by Economic Motors of Eynsford, in Kent. They were then selling it as an auxiliary unit for pedal cycles. The engine was a 154cc two-stroke flat-twin Johnson mounted over the back wheel, which it drove by chain. The Central Aircraft Co had been looking increase production after the end of the Great War, but failure to do so caused them to close
