AP49 - Manstopper percussion box lock pistol
Manstopper percussion box lock pistol. Unusually large .7” musket bore 6” barrel. Turn-off barrel with four opposed notches at the muzzle for a barrel key. Belgian made with Liege proof marks to action, which is naively engraved.  Plain and squared base butt, but with reinforced backstrap, no doubt because of the massive bore
