Initial BNC came from Bollack, Netter et Cie, the partners who created this brand in the twenties. Victim of the crisis like many others, BNC had to cease its activity in 1931 but it was taken over by André Siréjols (agent and driver-end only) who in his garage Levallois, continue a small-scale production of BNC 1100 with Ruby engine.
