superjet03:  Welcome to the KCA forum.  You better keep this rifle or find a better husband for your wife on this forum (I am not available, darn)!
  What you have is a Norwegian Model 1912 Carbine that was built at the Kongsberg Vapenfabrikk (Arms Factory) in 1924.  Someone altered your Norwegian Krag by removing the hand-guard and rear barrel band, re-shaping the front nose cap, and installing an American style 'ramp' front sight.  The intent was to make a military surplus rifle into a handier 'Mannlicher' style hunting carbine.  These changes damage the collectability of your Krag, but, it is still a dandy rifle for shooting and hunting.  All the serial numbers, that I can see, match (I can't read the number on your bolt).  Hopefully, your rifle has a good bore.  The 6.5X55mm 'Swedish Mauser' cartridge is a great one and growing in popularity in the U.S.  You should play with this rifle, as is, and bond to it.  Don't look a gift horse (from your wife) in the mouth!  Take her shooting and have a nice picnic and bottle of wine after the guns are put away.  (Attached picture shows M-1912 carbine as issued).
