.44 rimfire caliber, 20″ round barrel with “KING’S ” patent markings on the legend.  Full magazine with carbine front band and sight.  Lever action brass frame, walnut forend and straight grip buttstock ending with a crescent brass buttplate.   The barrel and magazine tube showing an brown/gray patina with smooth surfaces and crisp barrel address.   Nice mellow unpolished brass with strong edges and an even appearance.  Fine wood overall with some minor handling marks and a ding on the flat near the buttplate.  Original ramrod in the buttplate trap. Excellent bright bore and rifling.   Mechanically sound.  Very nice original 1866 carbine.
