Traditionally, British manufacturers concentrated on single-cylinder engines and left the marketing of four-cylinder machines to others until the success of the Ariel Square Four, introduced in 1930.

Many drawings of four-cylinder units were made, however, and occasionally, a complete machine would be produced for experimental purposes. This exhibit is one of them. It was deemed too expensive to produce for sale and remained in the secrecy of the experimental department for decades.
