In 1947 he followed his survey of the Seventeenth Paris Salon by a description of the Arsenal VB-10 CI as a preliminary It is perhaps natural, though regrettable, that up to the present the post-war French industry has shown a tendency to dissipate its ener to a full account, in June, of the interesting and varied work at that time proceeding at the French Government Establishment at gies over too many prototypes, but it seems that the lesson is begin Chatillon-sous-Bagneux.
