This is Chamelot, Delvigne 11 mm D.A. pinfire revolver. The mechanical function is very good crisp and tight. The bore is very good, bright and shiny with strong rifling. Only traces of original finish remaining. European pinfire was cutting technology from percussion. Then came the rimfire cartridge and the pinfire cartridge was finished in a very short time but was a very necessary step to the rimfire cartridge.
