This is one of a number of old propellers chosen by the museum's earliest curator, Paul Garber, from a collection at the Langley Field installation of the National Advisory Committee for Aeronautics in 1931. Although it was somehow identified as a Lavasseur (France) product, there is no marking to confirm its manufacturer. Both Lavasseur and Paragon (U.S.), for example, used blades with pronounced a S-shaped planform that twisted the blade as thrust levels changed.

The accession file notes without attribution that the propeller was used on the Spad VII aircraft. It is known that Levasseur built Spad XIII aircraft, but apparently did not build the Spad VII.
