The odd thing is the stock has a BSAT rondel, but the lock and barrel both have broad arrows signifying government used. Those two things don't go together. The barrel is also stamped for 24 gauge or 58 caliber, which would represent an gun made for a Union contract during the civil war. Standard British guns were marked 25 or .577 caliber. The VR under the tower is seen on British military owned firearms. Barnett did put VR under Tower on his locks, but no broadarrows. So all the defarbed markings seem to tell a confusing story. On PH used progressive depth rifling in the barrels. That's a sure way to tell if it's a PH. I can't really tell just looking at it in the pics.
