I didn't notice the bolt number mismatch, when first viewing your pictures.

Originally, the bolt number would have matched the receiver's.

Bolt #11805 was likely made in 1891.

The original bolt could have possibly gotten removed during WW2 Nazi occupation of Denmark or when rifle was shipped to U.S. Importer.

IMHO - 'Head-Space' is not as tricky with a rimmed cartridge, as with, a rimless one.

FWIW - The wood in your Krag's stock appears to be Elm. Scandinavian counties utilized some 'alternative' stock woods.
