 At the end of the 1920s they also started producing engines for stationary use, with the first model being the water-cooled WX11 and in 1933 the air-cooled Mar-vil.Villiers engines were also used in lawn mowers, for example the 147 cc engine was used in the Atco mowers of the 1920s and in 1931 it was joined by a 98 cc Villiers engine, known as the Midget.The Villiers company also had links to the Seagull outboard marine engines, both of which owed their existence to John Marston.
