RonC:  Your Krag rifle stock has been shortened by someone.  Not very likely by Springfield.  The barrel appears to be a carbine barrel. It appears altered to take a Krag Rifle Bayonet.  This alteration was done at one time by Bannerman, Stokes-Kirk, and others to make Krags useful for youthful students at military schools.  The U.S. Government did officially make a similar looking rifle for the Philippine Constabulary, but these were made on Model 1899 actions and are quite rare.  As someone suggested, your rifle was hot-blued by someone in recent times.  That finish does not take well to hardened gun parts and gives that weird 'bronze' finish.  IMHO, Your rifle's value is tied strictly to its utility as a shooter, around $300.  The re-finish harms its value as a parts gun.  It would be interesting to know the serial number on the receiver in order to find out if the action is in a known 1896 Carbine range.
