Your stock is a cut-down Norwegian military stock. Someone did a nice job 'converting' it into a handier rifle for hunting.

Restoration is tricky because Norwegian parts are hard to find and expensive. It is easy to put $1,000 into a rifle worth $700.

Norwegian barrels often have bores in poor condition. The barrel is hard to replace with its left-hand thread.

A 'restoration' would be a Mix-Master of non-matching parts and not desirable to collectors.

I would advise enjoying your Krag as it is.
