"0" grade lifter with twist steel barrels, left Parker factory late 1877 with 28" barrels and a pistolgrip stock. The case looks original and is worth @ what the entry level guns is if not more. VERY nice condition and should not be messed with other than have a competent smith give her a once over for shooting safely and use RST 2 1/2" light loads in her and enjoy. Best of luck, Jim DiSpagno
