From what I found on the interwebs Griffon bicycles were produced by from circa 1900 to 1927 by Les Fils de Peugeot Frères (Eugène) and after it was taken over by Société Anonyme des Automobiles Peugeot (Armand) in 1927 it became a sub-brand of Peugeot until 1955, when production in Courbevoie ended.
