Pre-war frame numbers are located on the front top frame member either near the front seat stay or near the steering head.
1950s models have the numbers located on the front downtube, either below or in front of the fuel tank. An exception to this is the early Bantams where the frame number is between the front engine mounting plate. ~ classicenglishbikes.com/

Les numéros d'immatriculation de la belle époque (1901-1928)
"September 16, 1901 begins the first French registration system. The management of this system is carried out by the Mines Department, upon receipt of the vehicle. This service is divided into fifteen administrative regions (maps) called mineral districts, the one of Marseille including in the first years the 3 regions of North Africa (Algeria, Morocco and Tunisia) as well as Monaco.
