Most French guns were made in St. Etienne; some in Paris. Boudier of Neufchatel would be the dealer who sold the gun. Hard to tell who made it, even if we had a look at the barrel flats. A lot of French guns were made "by the trade"; that is, by various craftsmen all working at their individual specialty (barrelmaker, stocker, actioner, etc). That's probably what you have. Doesn't mean anything good or bad about the quality--and, as noted above, nearly all French doubles are quite well-made. Just that it doesn't have a maker's name because, for the most part, French guns weren't made all under one factory roof, like Winchesters, Parkers, etc.
