Gosh, my vote fwiw on a pre "bike boom" frame like this is part out some of the non-original parts and replace them with later, but still French, parts. It is such a nice looking frame, with good chrome that just needs some TLC, and great looking original crank. Plus it seems the chrome "socks" front & back are an unusual bonus feature, as far as Automoto's go. Add a few decals from Velocal's Automoto selection and Voila!
