Don Truman saw the failings in the Marwyn which he had bought in partnership with Barbara Longmore (hence Bar Don) and developed the car himself during 1948 including a significant weight reduction, modified bodywork and smaller wheels to lower the car. It used a JAP engine. The Bardon-Turner came to be in 1950 when Jack Turner fitted alloy wheels, better brakes and independent suspension.

In 1948 trim, looking more like a Marwyn.

Same circuit, now piloted by David Ellison at the '99 Revival.

In 1952, Jack Turner built a new car in conjunction with Cyril Kieft using a his own design, double over head cam, four cylinder, engine however it did not produce as much power as was hoped and only two Turner Kiefts were built.
