This photo showing a model of a 'S.N.C.A.S.O. interceptor' project was published in 1955 in a Dutch aviation magazine (AVIA-VLIEGWERELD). Model was shown during the Paris air show at Le Bourget of that year.
I am a little bit puzzled: Jean Cuny's book 'Les Avions de Combat' Vol.1 mentions NOTHING on such a Sud-Ouest project. However, mention is made in the same book-with some illustrations- of the Nord 'Harpon' fighter project. Although not exactly the same, it shows a jet fighter with more or less the same canard configuration. Any Guesses??
