How often were Norwegian 1912 carbines produced in 7x57 calibre?

Most likely your Norwegian Krag was altered commercially in North America, at a time when 6.5X55mm ammunition was very uncommon.

It would be wise to do a chamber cast, because the head diameter of the 6.5mmX55mm cartridge-case is larger in diameter than the 7X57mm cartridge-case.

The barrel would have to be set-back one thread, to properly re-bore and re-chamber for the smaller diameter case.

Your Krag, #27510, was likely built in 1924, as a model 1912 carbine in 6.5X55mm caliber. (Caution - Norwegian barrels have a left-hand thread).

Thank you for the prompt reply. It is indeed stamped "1924" with Kongsberg marks and has had the stock 'sporterized'. I will do a more exact measurement of the barrel length, a chamber cast will take a little longer.

Oldcastle - I forgot my manners! Welcome to the KCA forum.

I could be wrong, but, I think your Krag has some added markings. The crowned 'S' on the barrel almost looks like a Sako (of Finland) marking.
Clear 'close-up' pictures of the circled marks might give a clue as to where the conversion work was done.

Attached is a photo of how your Krag originally appeared.

Thank you - glad to be here.
The rifle is not mine - yet. Negotiations are under way :)
Here is the top view showing the marks better.
The action is smooth and the general condition is quite good.
The obvious drawback is that the original sights are gone. I doubt if what is left of the rear mount will allow easy restoration.

Well, I am now a Krag owner. The serial numbers match and the barrel is 24 inches long. Now I just have to figure out exactly what this one actually shoots, given the comments about the conversion to 7x57.
