Looks like all of the same markings I have seen on some K98b Rifles I have even the firing PROOF looks like the mid 30s stuff I have on my early 98k and 98b rifles. Dean Sova (313)299-9533 I thought they ground all the markings on reworks?? Serial number is 4966 no suffix no grind marks nice and clean . Please explain the safety difrences you mentioned.
