Powered by a 310 hp Renault 456.
This aircraft had a unique propeller. I would have to call it a single cycle two position pneumatically controlled propeller. The twin engine de Havilland Comet racer had the same propellers. The following description of this prop is from a de Havilland book.
Ratier two-position airscrews were fitted to give optimum take off performance. They changed automatically into coarse pitch at 150 m.p.h., at which speed a disc on the spinner was forced back to release the 80 lb. of internal air pressure, but a return to fine pitch could only be made on the ground with the aid of a bicycle pump before each flight.
Carrying race number 100, this aircraft came to the USA and won the Greve and the Thompson trophy at the 1936 National Air Races.
As a teenager by father, H. E. Shumaker, must have been impressed by this aircraft. The following is a photo of him holding a model of the C.460 that he built, far right. This is a Vicksburg MS model airplane club. My Uncle Robert is the second to the left. I think Dad's model is the coolest.
