Two prototypes of the Fox VII "Monofox" were constructed as single seat fighters equipped with 6 machine-guns. The ventral radiator was moved backwards which gave the plane also the surname of Fox "Kangourou". One of both aircraft (O-136) was specially modified for Willy Coppens d'Houthulst, the First World War ace which was missing a leg. On this picture Coppens is standing to the right in company of (l to r) Mr. Tollet, Tips and Jacquet at Gosselies in 1937.
