De Havilland DH60GIII prototype G-ABUI
The prototype De Havilland DH60GIII G-ABUI with 120hp Gipsy III engine.
During 1931, the De Havilland Aircraft Company took the Gipsy II engine and turned it upside down, allowing for a cleaner, lower engine position and installation. This engine model was named the De Havilland DH Gipsy III (rated at 120 hp) and it was fitted to the De Havilland DH60G Moth airframe to produce a new variant to be known as the DH60GIII Moth.
The prototype DH60GIII (G-ABUI) flew for the first time in March 1932.

An improved version of the engine, the DH Gipsy IIIA, was produced in large quantities as the 130 hp Gipsy Major which powered many types of light aircraft types from the DH Puss Moth to the DHC Chipmunk (with a DH Gipsy Major Mk10). Once powered by this engine, the type then became known as the Moth Major.
A total of 154 De Havilland DH60GIII Moth aircraft were built with either the DH Gipsy III or DH Gipsy Major engines and of these, more than half were exported world-wide. Of those built, 10 were for the RAF as De Havilland DH82 Queen Bee Target Drones.
57 of the 154 were DH Gipsy III Moths with the majority of the remainder (96) being built as De Havilland DH Moth Major at Stag Lane.  The remaining example was built by the De Havilland Technical School.

Although not as famous for long distance flying as the DH Gipsy Moth, notable flights made by DH60GIII included Lisbon to Goa, Lympne to  Darwin, Calcutta to Leeming (Yorkshire) and New Delhi to Ceylon and back.
Production ceased in May 1935.
