            Taylorcraft Model D was tandem two-seat version of the Model
            B.  Introduced in late 1941, this aircraft was available with a
            65 hp Continental, Franklin or Lycoming engine. The US Army purchased the Model D as the O-57
            observation aircraft.  These aircraft were redesignated the L-2
            (liaison) in 1942.  A total of over 2,300 D Models were built. |  |
