M. J. Guillemin designed a high-wing single-engine light postal or ambulance monoplane, the J.G.40, shown on the Bleriot Aeronautique stand at the 1930 Paris Air Show. The latter company acquired the license to build aircraft. A two-seat light aircraft, the J.G.10, competed in the French Air Ministry Light Aeroplane Competition of 1931, but retired with engine trouble.
