Muzzleloading Kit pistols

They need some simple “do it yourself” knowledge basis, few tooling and some working hours to complete and finish a “self-custom-made” gun.
The KIT gun has been previously assembled, the barrel is not blued but it goes through an antirust treatment, the lock is assembled and finished, the stock needs to be smoothen, checkered, coloured and oil finished, the metal furniture needs to be polished.
