I've owned many Indian items over the years but without a doubt this is the best.  It was found in a Montana cave a few years ago which explains the supple condition of the scabbard.  The buttstock had it's buttplate removed (hide scrapper) and retains a period Cross and stick figure of a man.  I'll let the pictures speak for themselves. Being found in a Montana cave this Indian Arm may very well have been at the "Battle of the Little Big Horn".
