A Brief History of the Marque
Built by SNCAN (société nationale de constructions aéronautiques du Nord), the 3-wheeled Inter microcar used an Ydral engine.
SNCAN was a company created during the nationalisation of the manufacturers of war material in 1936. It was constituted by the regrouping of the factories Potez, ANF Les Mureaux, Amiot and Bréguet. In June 1949, it absorbed SNCAC and became Nord Aviation after the absorption of SFECMAS (French Society for the Study and Construction of Special Aeronautical Materials) in 1954. (Wikipedia)
An advertisement was published in the Revue Technique Motocycliste of March 1955
