Found a unique one and almost let it go. Today I found a Mosin Nagant Rifle, Single shot, .22 cal. Had never heard of one until this one found its way into my hands. English markings, 11 inside a circle with what looks like PK and a 1 below the PK inside a diamond. Year is 1955. Anyone have info on where it was built or how I can find out more about it?
