| The
            Wright-Martin Aircraft Corporation was formed in 1916 to make Hispano-Suiza engines under license.  Large numbers of the Model
            E (the Hispano-Suiza 8Aa) were produced with minor improvements.
             The last of the E model engines, the E-4
            Tempest was the main product of the new Wright Aeronautical
            company when it was formed in 1919.   |
