It appears you have a Norwegian Carbine - Model 1897 for Mountain Artillery and Royal Engineers. It is serial number 6,226, made in 1902 at the Kongsberg Vapenfabrikk (Arms Factory). On your receiver, above the 1902 date, is a stylized "K" and Crown, for Kongsberg.

The carbine would be in 6.5X55mm caliber, (commonly called '6.5 mm Swedish Mauser').

The Stock 'checkering' is not original to the arm and appears 'crude home-craftsman' for 'Hunting'.

The metal 'eye' sticking out of the Stock Butt is for the Military Sling, which utilizes a 'snap-hook'.

Value of your Norwegian carbine would depend on bore condition and completeness of the rest of the rifle. The value is damaged by the bolt mismatch and 'homespun' checkering.

'missedagain':

I didn't say your Norwegian carbine "wasn't worth much". I said the 'checkering' and 'mismatched' bolt lower its value.

Norwegian Krags are often encountered in North America with mismatched parts. Also, bore condition is often poor.

That said, Norwegian Krags are hard to find and they are chambered for a very popular cartridge.

A nice bore would raise the value and utility of a Norwegian Krag.

These rifles can have considerable parts value and restoration value.

You said the rifle is "inherited". Is it a 'Family Heirloom'? (Hard to put a value on that).

You also did not show us very much in your photo. (Makes it hard to estimate a value).

Norwegian Krags are desirable, hard to find, and expensive. Don't be too hasty.
