Chevallier et de Cleves

   A Bleriot-type monoplane appears in at least one photograph labeled Lechevallier; it may be another design by Yves Chevallier of CPC. Unlike the Bleriot XI, the machine had long skids forward of the main wheels, and a rectangular rudder with the 2 aft corners clipped. Chevallier and de Cleves were the French representatives for the Labor firm.
  

Chevallier, Yves

   Perhaps the same designer as the Chevallier above, this one designed and entered a remarkable pusher monoplane in the Concours de Securite in 1914. It had elliptical wings, a long flat triangular tailplane with no vertical surface; the engine was set amidships in the streamlined fuselage behind the trailing edge, the pusher propeller turning in front of the tailplane. 2 wheels and a short skid supported the aft end.
