Hello i would like to know if this sight is a norwegen krag sight any books i have does not have the markings in any of my books . Thank You Scott

I too have just obtained a Norwegian Krag, but am not sure how to post a photo using the system of buttons above - I'll know when it goes!.  I shot the rifle yesterday and could not figure out for sure how to adjust the windage on the rear sight.  It appears to require having a special two-pronged screwdriver tool to turn the tiny adjusting screw - does this sound right, experts?
In shooting I tried to use up to 20gr of 2400 behind a looong 160gr cast GC bullet.  I got keyholing, worsening above 18 grains.  So I am going to try lower loads from 15 to 18 gr.
Thoughts?   
Thanks,
tc

'TCINALASKA' - Welcome to the KCA Forum.

That is a Norwegian rear sight. By its placement on the barrel, your Krag must be a Model 1912 Carbine. The serial number range for "Karabin"s made in 1916 would probably run from #8,752 to #16,678.

Possibly, your 'bullet tumbling' could be a result of poor bore condition. You might want to try some reloads with 139 grain jacketed bullets.

You can make a spanner for your rear sight's windage-adjustment screw by grinding and filing a pair of 'tines' on an old screwdriver tip.

I took the liberty of reducing the size of your photo and I am also attaching a picture of a Model 1912 Carbine.

Thanks - and yes it is one of the 1912 versions with serial number just shy of 9840, so an earlier one.  I have obtained a replacement front band/bayonet lug of the one-piece variation, which I understand was a characteristic of the 1912/18 model.  I have some scrap wood, and the middle band w sling swivel, so now am staring at any picture I can find of a 1912 to get the best understanding of the dimensions of the final upper and lower parts of the forend wood - which was "sporterized" away in the past.   
Thanks also for confirming that one adjusts windage only with a spanner that fits - I expect that was to discourage riflemen fooling around with windage if not in a stable environment?   
And can you explain why the little pin is in the upper part of the barrel between the rear sight and front, why sticks out the upper handguard wood? 

I have a 1916 bayonet/scabbard, and am seeking a replacement sling.

Thanks

Hello there... How about some more pics. of your rifle?

The notch you see on the underside when you flip the sight forwards is for 500 meters. This is the point were the trajectories of the old and new ammo meet. The original bullet was called “B – spiss” or “B – prosjektil” (projectile). (spiss means point or "spitzer"). It was a 156 grain roundnosed bullet. Johan Enger of NORMA supplied a new bullet for trials in 1910. (He was one of the brothers who started NORMA in 1894. He was also one of the leaders of the norwegian shooters movement. He had Krags fitted with scopes and set up trials for the army in 1905, wich resulted in a Krag sniper adopted in 1910, 1000 snipers were  made). (You need to Login to view media files and links)
The tests with the new NORMA bullet were very positive, but the long rifles and short carbines got different POI. The development of a "short rifle" started at the same time. The result was the M/12 carbines. The ammo question was postponed until the M/12 was finalized. Then came WWI and things were put on ice again, but finally in 1925 the new round was adopted. The new bullet were called “D-spiss / D-projektil”. It was a 139 grain boattailed spitzer. V0= 750 m/s.
From 1925 and onwards, all sights were modified for the new bullet. The M1912 carbines got that extra notch for the old bullet as well.

??Only one of the photos came thru - here are others...maybe.

Here are the parts, bullets...
