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.

Although the scalloped leading edge protection apparently identifies the artifact as an Army propeller, it is not possible to further provide identification without additional information.
