BNC
BNC which stands for Bollack, Netter & Cie was started by ex Hispano-Suiza man Lucien Bollack, who produced cyclecars with engines up to 1100cc manufactured and supplied by the firms such as Ruby, SCAP and Chapuis-Dornier, sometimes with Cozette supercharging. Cyclecars had been made popular in France by the law allowing a 2 seater car which was under a dry weight of 350kg and 1100cc capacity to run with minimal yearly taxation. Think of GN, Amilcar, Salmson or Lombard (BNC took over the stock of Lombard in 1929). BNC eventually ran into financial trouble when it tried to go "upmarket" with an 8 cylinder large capacity car. By 1928 Bollack and Neter had gone and BNC taken over, but even the new owner struggled to cope with the world economic depression of 1929, so after making various prototypes the doors finally closed in 1931.
Tyre sizes for various BNC models were:
- Type F, the first model from 1926 , tyre size 26x3 (this is the same as 700x80 tyre size)
- Type FX from 1927 tyre size 350x19
- 1927 Monza and Montlhery models had tyre size 400x19
- Type HD and Type 51 from 1927 were listed with tyre size equivalent 450x19
- Type 53 is quoted in period supplied with 400x19 and 450x19 equivalent sizes.
See below all the tyre sizes we know were used on the various BNC models, including the beaded edge sizes 700x80 and 710x90:
