Walter Watney, appointed Chairman of the Board of Directors of SAFAD decided to establish his own racing team at the end of 1938. For this, they built two cars bodied by Olivier Lecanu-Deschamps and powered by the six-cylinder 3-litre Delage engines. These two cars competed in the 1939 24h Le Mans and one of them - # 21 driven by Louis Gerard and Georges Monneret - led the Bugatti 57 G tank for much of the race. Finally, he finished second in the general classification and won the category 2 to 3 litre.
