https://en.wikipedia.org/wiki/Austin_Whippet

The Austin Whippet was a British single-seat light aircraft designed and built
by the Austin Motor Company just after the First World War. It was a small
single-seat biplane, intended to be an inexpensive aircraft for the amateur
private pilot, and a small number were built before Austin abandoned aircraft
production.

In 1919, John Kenworthy, chief designer of the motor manufacturer Austin Motor
Company, (who had built large numbers of aircraft under license during the First
World War) designed a small single-seater light aircraft in order to cash in on
an expected boom in private flying. The resulting aircraft, named the Austin
Whippet, was a small single-seat biplane of mixed construction, with a fabric
covered steel tube fuselage, and single-bay, folding wooden wings. The wings
avoided the need for rigging wires by use of streamlined steel lift struts.

The first prototype, powered by a two-cylinder horizontally opposed engine, flew
in 1919, receiving its Airworthiness Certificate in December that year.
Production aircraft were powered by a six-cylinder Anzani air-cooled radial, and
four more aircraft followed before Austin abandoned aircraft production in 1920,
when it realised that the postwar depression was severely limiting aircraft
sales.
