Brief History of the Marque: Rex Acme
Founded by brothers William and Harold Williamson as a car manufacturer in Coventry in 1899. In 1904 they turned to motorcycles building 456cc singles and 726cc twins. Made the first telescopic forks in 1906, and introduced several other innovations including rotary-valve engines and in 1908 were the first to angle the top tube downward to lower the riding position. Company fired the founders in 1911 and under new boss George Hemingway went on to make own engines, as well as producing a series of JAP-powered machines for Premier. Took over Coventry-Acme in 1919 to become Rex-Acme in 1922. The range included 15 models by 1926, from 172cc to 746cc capacity, but as the depression deepened sales decreased. Sidecar manufacturer Mills-Fulford purchased the company in 1932, but dropped motorcycle production the following year and shortly thereafter ceased manufacture of sidecars.

Does anyone know WHERE in Coventry the Rex factory was? I believe it was Osborne Road, but when did it cease to be the Rex base, and what did the factory produce after Rex closed?

Or is it an Ackland of Southampton? My info, and I suspect it is wrong, is that Ackland were acquired by Rex-Acme [?Rex & not Rex-Acme] and info that Ackland existed from 1914-1924 is quite wrong in which case where did Tragatsch get his info. Any thoughts? Bruce Main-Smith
