Propeller, Fixed-Pitch, Two-Blade, Wood


Display Status:

This object is not on display at the National Air and Space Museum. It is either on loan or in storage.

Collection Item Summary:

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.

There was no other identifying information available for the artifact. However, its diameter and number of bolt holes may indicate the propeller to be a post-World War I or "modern" design as noted by the Wooden Propeller Forum.
