Hi there first time thread, I really enjoy the forum!

I was wondering if anybody knows anything about these markings? And if it's chambered in regular 8x57 or the older 8mmj.
Anyways it will be sent off to a gunsmith for verification. Btw I'll upload a pic of the entire rifle tomorrow.
Everything matches, right down to the action screws. Thanks for any help! (Hopefully my pics work)
