Collection Item Summary:

The markings on the artifact indicates its manufacture by the Davenport Brown Co. of Somerville, MA. The propeller was built to a specification of the Bureau of Aircraft Production (BAP), a U.S. Government organization that briefly existed in the World War I era. It was to be used on a Curtiss J4NH aircraft powered by a Hispano-Suiza engine built under license by Wright.

Davenport Brown was apparently one of the many companies of the era that assisted the war effort, but was not normally associated with aviation. There is evidence that the same, or very similar, propeller was also manufactured by the American Propeller and Manufacturing Co., a company that is historically associated with the aviation industry.
