I noted the rather "meaty" knurling on the bolt knob (grasp) which means this was possibly made for a hunter in Countries where cold weather hunting is the norm- much easier to grasp when wearing a glove or a mitten on the trigger hand, I should think. I also agree with the vise marks- I have beaucoup vise-grips in my tool boxes, they all have straight across cut jaws, not at a diagonal--From the imprints, I surmise the barrel receiver group was not through hardened?? Any thoughts on this? Fox!!
