History of the BNC 527

Bollack Netter et compagnie was founded in 1923 by Lucien Bollack, born in 1892, and René Netter. The works stood at 86–90 rue des Frères-Herbert, today rue Édouard-Vaillant, in Levallois-Perret on the northern edge of Paris. The firm closed in 1931 and was partly absorbed into Lombard in 1929.

Light cars were the company’s business from the first year: BNC took part in the second Bol d’or automobile in 1923. Out of that programme came a series of racing models, of which the Super Sport, the FCD and the 527 are the best remembered. The 527 was the 1.1-litre car, entered in the 1,100 cm³ classes that were popular in France between the wars.

The car’s record is spread across the French sporting calendar. In 1925 Henri Billiet drove a BNC 527 1.1 l in the hillclimb of the Col de Peyresourde at Bagnères-de-Luchon, in the Pyrenees. In 1929 Violette Morris finished sixth in the Prix de la Ville de Reims at the wheel of a 527 with a SCAP engine, and in 1931 Girard took fourth in the 1,100 cm³ class of the Circuit du Dauphiné on a 527 Ruby.

The 527 was also part of the marque’s endurance effort. BNC entered the 24 Hours of Le Mans eight times between 1928 and 1935, the best result an eleventh place for Adrien and Albert Alin in 1933, and the 24 Hours of Spa seven times between 1928 and 1934, with Michel Doré and Treunet eighth in 1932. The firm’s earlier cars had already won their class at Spa in 1930.
