'ARKLITE' - Your serial number, #7,593, confirms your Krag to be a Norwegian model 1912 carbine, built in 1915. The barrel, as issued, was 24 inches long.

(Photo of another model 1912 carbine with a 'flat' bolt-knob. The trigger-guard had provision to 'snap' the sling at the front of the guard. Also photos of original sights).

p.s. - Thanks for acknowledging my response. A lot of people don't, these days. I am always glad to help.
