When it comes to frame IDs, in most cases, the best one can hope for is to be able to say that the features of a mystery frame are consistent with this manufacturer or that artisan. Or, if you're non-committal, that features aren't inconsistent with a certain known marque.

As for the suggestion that this is a Cycles France-Loire; it could be. Did the person who made that suggestion provide more conclusive supporting evidence? If so, it'd be great if you could post here, for future reference.
