We copied this haversack from one in our collection though you have several options to choose from as those found on other extant originals. Each comes with a separate, internal liner bag. We can paint them with either our period paint recipe (Boiled Linseed Oil, Turpentine, Lamp Black, Japan Dryer) or modern (Black oil based paint) Please note that the strap length on ours is 42". If you need a longer strap, please include the desired length in the Notes section when placing your order.
