Charles: It would be 'instructional' to see a close-up picture of your Krag's front sight and muzzle area.

This would help identify if your barrel is a real Krag cabine barrel.

BTW - A Krag carbine barrel measures exactly 22 inches from muzzle to closed bolt-face. (Best measured by inserting and marking a cleaning-rod, from the muzzle with the bolt closed).

I would guess your Krag's re-sale value at around $750, based on parts value.

As a 'fun shooter' with its excellent bore, you will find it priceless!
