Boy, that Krag Carbine sure looks clean and in great shape! Can you give a close up of the receiver with its serial number? That will give us more to go on.

You do have a nice original 1901 carbine rear sight. The hump in front of the sight on the hand guard protects the sight when shoved into a scabbard used when on a horse and slinging the Krag. The hand guard does look to be a slightly lighter color than the stock but that's just fine.

Great to hear that the bore is in good condition. It should be a great shooter if you choose to do so. Most of us love to reload and shoot our Krag rifles and carbines.

The sling swivels are add-ons but I don't know much about the Engineer Krags. Someone else will inform us about those.

Congratulations with your new purchase and welcome to the KCA.! This is the best place to learn about your new Krag obsession.
