1920 Following the cessation of hostilities, the company's undue reliance on military orders became a handicap and the company became bankrupt in 1920. Its assets were bought by the Birmingham Small Arms Company (BSA) which did not pursue aviation-related business. The aviation-related assets of the company were bought by Geoffrey de Havilland and he formed De Havilland in the same year.
