That is a beauty and looks like another well made french boxlock. Very gracefull scalloped action. Engraving very much to my taste. Your barrels are marked exactly like mine.
Leopold Bernard Paris 1832-1870 rue Marbeuf, rue de Villejust, avenue de Versailles." Seit 1849 beruhmt fur damastlaufe". Obviously a damas story.Not surprising for a barrel maker of the time.
Roblin Ernst Gabriel, Paris 1872-1880, rue Ville-EvequeI hope it will help you.
Always intersted to hear about your Ideals .
Best regards
Geoffroy (Gournet)
It looks like Barnard barrels were made even later then believed
