This 50 caliber cannon features a 5 inch long steel barrel and measures around 9 inches long overall. The barrel touch hole is drilled into the bore, but I would recommend caution if you plan on firing this piece. Cannon remains in excellent condition with one age check in right wheel and a chip from right hub. Wood parts show an old oil finish, the barrel and hardware show a nice dark patina. A very nice display item. Free shipping.
