Gray Motor Company

Gray announced their line of horizontal hopper-cooled engines in 1911. This followed a 1910 takeover by the United States Motor Company, an automotive conglomerate that failed within a few months. When Gray resumed operations under their own leadership in 1911 the farm engine line appeared. This 1 3/4 horsepower “Marvel” of 1914 followed an earlier 1 1/2 horsepower style. A full history of United States Motor Co. appears in Crestline’s 70 Years of Chrysler by George Dammann.
