I have a 1976 200th year of American Liberty Ruger single six .22 / .22 Mag with red velvet extra cylinder bag and white and red box for the cylinder with the 9 1/2" barrell. Gun is in what I call good shape, my dad bought it new in 1976 and the only wear is blueing wear where it has been slid in and out of a leather hog leg holster for all those years, gun has no rust and action is crisp and clean. What would the value of this gun be ? It has killed many a wild hog in its day !!!!!!!
