'carbon outlaw' - If I understand your question, you are not at all familiar with this Krag variation?

The barreled action is from a Danish model 1889 Krag-Jorgensen rifle, that was made in 1911.

I can not tell from your photos if the barrel is an altered Danish barrel or some type of re-barrel.

The original chambering would be for the rimmed 8mm Danish cartridge. The Danish barrels used a form of rifling similar to Medford Rifling ('Rasmussen Rifling').

IMHO- It is easily worth $50 for parts and conversation.

More information can be found in 'photo tab' on KCA pages and in past threads under 'European Krags'.

p.s. - It appears part of the 'follower' is missing or altered. This suggests possible alteration to feed a non-standard cartridge.
