hello all, Hoping for some help with this one.. I am fairly certain its a Norwegian Krag, it is chambered in 6.5x55 but not marked anywhere i can find

This was my grandfathers firearm and i am quite sure it is not a "sporterized" krag. I believe it came this way.. the only other one i've seen is on some auction site and is mislabeled as a "sporterized" version.. would love to see if anyone here has some info they can share.

Markings on the Firearm

- Letters AA are on the switch that controls if you are pulling rounds from the trap
- Markings D and B are under the rear sight. as well as some other marking in between them that i do not know what it is.
- there is a T marked in the side of the barrel
-10221 in the metal butt plate
- 20752 stamped into the barrel with other hallmark markings.
-1918 stamped on the top of the barrel below the

other unique piece is the trigger guard has a hole on the front side of it..

'OneGuy' - Welcome to the KCA Forum.

You have an unofficially altered Norwegian model 1912 carbine. The stock has been cut-down ('sportered') and a sling and commercial swivels were added.

Near the 1918 date is a 'Crown & Stylized K', this indicates manufacture at Kongsberg Arsenal, Norway, in 1918.

When first manufactured, all of the serial numbers on the carbine would have matched #20752.

Attached photo shows original appearance of a Norwegian model 1912 "Karabin". The Norwegian Sling has a 'snap-hook' which allowed it to be attached to the "eye" mounted on the Butt or at the hole on the front of the trigger-guard.
