A Brief History of the Marque
Manufactured from 1919 to 1920 in Argenteuil by Georges Levy and Maurice Le Pen. It is believed they were fitted with JAP engines.
After the death of Le Pen, in 1920 the company was sold to Orial in Lyon which changed to MAG engines and branded the machines as their own.
