The vast majority of overdrives in European cars were invented and developed by Captain Edgar J de Normanville (1882–1968), and manufactured by the English company Laycock Engineering (later GKN Laycock), at its Little London Road site in Sheffield. The system devised by de Normanville was adopted and manufactured by Laycock after his chance meeting with a Laycock Products Engineer. De Normanville overdrives were found in vehicles manufactured by Standard-Triumph, who were first, followed by Ford, BMC and British Leyland, Jaguar, Rootes Group and Volvo to name only a few. Another British company, the former aircraft builder Fairey, built a successful all-mechanical unit for the Land Rover, which is still in production in America today.
