It is an Oméga-Six, built in Boulogne-sur-Seine. First shown at the Salon du Paris in 1922, the 12 CV featured a 6 cylinder engine of 1996 cc (65 x 100 mm) with a single overhead camshaft and a double carburator. The engine was developped by Monsieur Gadoux, who also worked for Hispano-Suiza. In 1926, a 14 CV was added to the range, also with a 6 cylinder engine, but with 2.6 litre displacement (75 x 97 mm). The Oméga-Six had a good reputation because of their comfort and some victories at road races, but they were very expensive.
