Passerat et Radiguet
Automobile-body makers and propeller-makers since 1909, Passerat and Radiguet introduced their monoplane at the 1910 Exposition in Paris. It resembled a Bleriot XI with a stalky 4 parallel-strut undercarriage supplemented with Bleriot-style looped bamboo canes for a skid. Oyster-shell wing-tip ailerons were fitted. The engine was a 4-cylinder radial Berthaud.
By 1911 Berthaud had built a copy of this machine, very likely of metal, referred to as the Moreau-Berthaud Sylphide. At the same time Passerat and Radiguet announced they had registered a design to compete in the 1911 Concours Militaire, but this machine never appeared.
