Andreas - the one I referred to had high standing cap=-lock hammers for the top barrels with nipples sticking up too high. Yes - it is a muzzleloading pistol, at least for the top barrels. Being a 4 barreled gun, perhaps the bottom barrels are supposed to be ctg. I cannot see it being a real gun. I've never heard of one like that, - guess it's certainly possible. The gun I mention is not the one pictured amongst the ctg. Howdahs, the 4 barrel Lancaster, for instance, but a different & much heavier, larger gun gun entirely.
