double gun 0,64" Randschluss but rechambered to 20/70, needles probably grind down into firing pins SN 234134 http://egun.de/market/item.php?id=5952109

but ... the stock although looking interesting is again not original anymore. you see on the first view it lacks the quality of a 19. century gentlemans gun especially the checkering. the damascus barrels while looking very thick are maybe not the best thing for shooting smokless loads.
