HALL-SCOTT

'Hall-Scott' was a Berkeley, California-based manufacturer, among the most significant builders of water-cooled aircraft engines prior to World War I. It was founded in 1910 by Elbert J. Hall and Bert C. Scott, initially to produce powered passenger rail cars. Hall-Scott aero engine production also began in 1910.
Shortly after WW I, Hall-Scott dropped its aero engine and rail car product lines. The firm produced several hundred thousand two-speed rear axles for the Model T, the Ruckstell Axle, through the mid-1920s. American Car and Foundry purchased Hall-Scott in 1925 and used its engines in its buses and boats. In 1931, one of the firm's most famous and important products, the Invader, a marine engine, entered production. The company attained its highest production and employment numbers in World War II, building engines for a variety of military boats and a tank retriever.
ACF divested itself of Hall-Scott in 1954, and the division was purchased by Hercules Motors in 1958. The final products bearing the Hall-Scott name were produced by Hercules in the late 1960s.
