'Phoenix1647' - Welcome to the KCA forum.

The serial number of your Norwegian Krag, model 1895 Cavalry Carbine, is #1557.

Your Krag was built at the Kongsberg Wappenfabrikk (Arms Factory) in 1899.

The script "K" with a Crown is the marking for the Norwegian factory at Kongsberg.

Your carbine is chambered for the 6.5 X 55mm cartridge, (commonly called 'Swedish Mauser').

Unfortunately, your stock has been altered. The forearm tip has been shortened. The barrel-band and rear 'sling fixture' have been discarded.

A careful and knowledgeable 'restorer' could probably return things to the original appearance, if the correct rare parts were found.

If you look at the thread (Buckstix), directly below yours, you can view a similar Norwegian carbine and get an idea of what is missing.
