The Green Engine Co of London
The Green Engine Co was an early British engine manufacturer. It was founded by Gustavus Green in London to produce engines of his design during the first decade of the 20th century. Actual manufacturing was carried out at the Aster Engineering Co. The firm produced a range of water-cooled, in-line engines up to about 1915. Green engines powered many pioneering British aircraft, including those by Alliott Verdon-Roe of Avro, and the Short Brothers
