It was completed on 2 September 1936 and sold to Victor Rothschild, 3rd Baron Rothschild. Painted a metallic gray-blue, No. 57374 was supposedly built using various components from the Aérolithe prototype, the most notable being the chromed elements on either side of the engine grille. In 1939, at the request of Victor Rothschild, the car was brought back to Molsheim in order to have the "C" specification supercharger fitted. He used the car until October 1941, when he abandoned it in the middle of a field after the engine exploded due to the malfunctioning supercharger that was fitted two years before.
