This engine, built by the Glenn H. Curtiss Manufacturing Company of Hammondsport, New York, about 1907 is believed to be a Model C-4 or D-4 engine. The Model C-4 was designed specifically as a power plant for a U.S. military dirigible. It was built as a light aeronautical engine and was fitted with mechanical valves and auxiliary ports. A propeller was connected directly to its drive shaft.
