This is at the store and restoration site for the museum. From the museum website: built in 1927, the Museum's FB-5 came to us as a donation, consisting of a few miscellaneous parts, an engine shell and a cooling radiator. The remainder of the aircraft components have been created by our volunteers in the restoration and machine shops at Gillespie Field and Balboa Park. When completed in 2020, this very rare fighter will take its place as one of the dozen or so built from scratch (virtually) aircraft in the collection.
