A lot of the double rifles were made in areas where, after the Civil War, there were still bears and other large game that often required more than one shot to stop them...Michigan and upper New York, and lower Canada produced a number of these...but they were made elsewhere as well, even in Kentucky where I collect. I think the guard is original and OK on this double rifle...note there are no pin holes in stock so wood screw attachment is original to gun. The very high, strong comb is more often found on southern guns, and the large moon inlay in the butt, behind where the cheekpiece would normally be, is often seen on southern guns...North Carolina and Kentucky come to mind. 'Unfortunately, these later weapons are less distinctive and harder to place, despite the neat comb inlay and barrel initials. Shelby Gallien
