Collection Item Summary:

From the markings on this artifact, it was built by the Warner Aircraft Corporation of Detroit, Michigan, but designed by Ole Fahlin. Warner built four models of similar radial air-cooled engines. The company existed from 1927 until 1950 when its assets were sold to the Clinton Machine Corporation.

Ole Fahlin was a Swedish born aviation enthusiast who learned to fly in Germany, was a pilot in the Swedish Royal Air service, and came to the U.S. following World War I. Frustrated with the propeller on a surplus Curtiss Jenny he barnstormed with in the Midwest U.S., he designed his own and achieved improved performance. With a well-known reputation as a propeller designer, he began a manufacturing business in Minnesota. He later moved the company to Marshall, Missouri when offered a larger property allowing greater production during World War II. He moved to California in 1962 where he later consulted for Lockheed Aircraft.
