1929 Curtiss Condor 18/CO/Model 53, developed from the Model 52/B-2 Condor bomber. Glenn Curtiss made his last ever flight in a Condor on 30 May 1930, to commemorate the 20th anniversary of his 1910 flight from Albany to NYC. After retirement from Eastern Air Transport (who got them for way below cost in the absence of any other customers) four of the six built were used by Clarence Chamberlain for barnstorming tours in the mid-1930s.
