I have a 15 bore muzzleloader that Mr. Highsmith reconfigured for me. I'm a lefty and he had bent a couple of gun for me previously. I asked him after that to keep on the lookout for a small bore ML shotgun that I could shoot. Six months later a package arrived from him. The gun has Osborne barrels and the locks are marked "MH Blood, Memphis". The stock is cast on to my dimensions. The breech plugs were removed and re casehardened, as were the lock plates and hammers. All remaining metal is rust blued. The wood has High's signature alkanet red stain. I have shot a lot of doves with that gun using an ounce of shot and a light charge of black.
