Collection Item Summary:

Farm boys Harry and Martin Sensenich constructed an air driven wagon using an old aircraft engine and propeller. Lacking funds to repair the propeller following an accident, they built their own. From this experience, the Sensenich Brothers Company was born in 1932.

With World War II experience from volume production for military trainer aircraft, Sensenich became the largest producer of wooden, fixed-pitch propellers for light aircraft from manufacturers including Piper, Murphy, Diamond, Cessna, and Beech.

This artifact is from the collection of Mary E. "Mother" Tusch who, as a result of her motherly association with pilots who trained near her home at the U.S. School of Military Aeronautics at the campus of the University of California at Berkeley during World War I, became an avid supporter of aviation and aviators for much of the 20th century.

From the markings, the propeller is likely for a Continental C90 engine, typically used on Piper, Aeronca and Cessna aircraft.
