This is an interesting Civil War period Enfield "M" Rifle.  It shows moderate wear with numerous dents and dings in the wood but no disfiguring pitting except maybe on one swivel.  It has a brass trigger guard, butt plate,  nosecap,  what appears to be an American walnut stock, is complete with rear sight and ramrod.  The lock is marked 1861 forward of the hammer and Eagle over "M" within a shield to the rear and the barrel has no proof marks.  The iron parts have a smooth, natural brown patina and the brasses are lightly tarnished.  The gun is actually an odd length.  The barrel is 35 inches long with a good bore.  It has certainly been in this configuration since the period of use.  It has lost its bayonet lug on the right side of the barrel and the end of the ramrod is properly threaded.  An interesting Civil War Rifle.  SOLD!!
