W. Richard's 10ga S x S Double Barrel Black Powder Twist Steel Barrels. The barrels seem very good but it is up to you to have them checked out by a professional gunsmith. It was always my plan to use this on roosters but with 40 or more Shotguns I don't think I will ever get around to it so I am letting it go. The stock has very nice tiger striping in it. The stock was professionally repaired years ago. Then it was rechecked and refurbished. A different horn buttplate was fitted.
