After all the info, research, and catalog scans, it matches nearly every spec for the 1974 model, the only exceptions being the headset is Campy instead of the spec'd Stronglight, (Could be a factory substitute, since this model was in the 2nd tier spot, only behind the Le Champion model, which did have the Campy headset), and it has a Maillard freewheel instead of the spec'd Atom model. Every other detail, including Sedis chain, matches the '74 catalog.
