The original engine was one of the first engines constructed by Gottlieb Daimler and used in a very early motor carriage "The Motorkutsche". This engine was called the "Standuhr". It was the first "fasr running" petrol engine ie it ran at about 700 rpm.

Unusual in this engine is the method of valve operation, a disc with grooves in place of the more familiar cam.

The de Havilland Gipsy Major is a four cylinder, air cooled, inline engine used in a variety of light aircraft produced in the 1930's including the famous Tiger Moth biplane. Many Gipsy Major engines still power vintage aircraft types worldwide today. Engines were produced by de Havilland in the UK.
