Motorcycle engines from France, Britain, Germany, Switzerland...
Brouiller engines were supplied to Bon Avion, Moto Montée, B & P and others.
Microma In 1947, Mignon, Croleak and Malaprade developed a motorcycle engine based on a Gillet-Herstal unit. The single-cylinder four-stroke disc-valve "turntable" engine had no poppet valves, the disc being driven via a shaft and bevel gears, one assumes. Information is very sparse. The Austrian Freyler engine used a similar concept in 1928-29. Source: Wikipedia NL (NIT)
Morris engines were fitted to Hobart lightweights in 1922
Piazza and Ladetto & Blatto engines were used on a variety of Italian machines.
SMW, Bosch Stockdorfer Motorenwerke AG, Stockdorf, near Munich. This engine was used in the early 1920s by Bison, Linsner, SBD, and the wooden-framed Hirsch.
Vickers, the arms manufacturer, supplied engines to Royal Enfield in the years following WWI.
Whitley engines were supplied to Mills and Fullford in 1903-1904.
An Aluminium Engine.
Another good unit for assemblers is the Bergmann, a V type with aluminium cylinders, having steel liners and vertical overhead valves directly operated by an overhead camshaft, no gear being used between the cam and the valve stem. This engine has a cast iron detachable head, and is built as a unit with the change-speed gear. It is the work of one of the most reputed German engineers, and is undoubtedly a fine piece of work.
