The problem was solved for De Havilland by the Air Disposals Company (Airdisco), which had got hold of a large number of Renault air cooled V8 engines, that were surplus to requirements. They converted them to four cylinder engines using a new crankcase.
The Moth was so successful that by the late twenties, the end of the engine supply was in sight, so De Havilland hired Airdisco's chief designer (Frank Halford) to design a new engine based on the Airdisco engine, and with as many common parts as possible while making improvements. This was the DH Gypsy engine. Slightly enlarged and inverted it became the Gypsy Major, fitted to many DH aeroplanes in the 1930s, including the DH82A Tiger Moth, which was used in very large numbers by the RAF and the Empire Training Scheme during WW2. Over ten thousand of these engines were made in Australia, as were just over a thousand DH82As.
Because of the requirement for parts commonality with the existing Renault conversions, metric threads were used.

They use Imperial threads.Quote:

CAC and GAF don't get mentioned. James Kirby was apparently a close personal friend of Lord Hives, Chairman of Rolls Royce.
New Question:_
What car in 1927 was the first front wheel drive car to use CV joints, and what type of CV joint?
(Hint, there is a Landrover connection)
