E.N.V. (or ENV) of Paris and Courbevoie, Seine, France, and Sheffield and Willesden, England.
The London and Parisian Motor Co. was an Anglo-French company registered in London in 1908, largely supported by British capital and expertise. The engine parts were produced in Sheffield, where the company was originally based, then shipped to France for assembly, where aeronautical activity was more important, but where, in 1908, imported machines were subject to tax. The French factory was located in Courbevoie, a suburb of Paris. In 1909, interest in flying greatly increased in Britain, and the ENV company decided to undertake complete manufacture in Willesden, London. The business at Willesden was named ENV Motor Syndicate Ltd. The name was derived from the French 'En-V' meaning a Vee engine layout.
