I've got three surplus Garand bolts in GI grease paper wrap...two 12SA and one 65 series and none of them have the Rockwell hardness punch. I've heard but can not confirm not all bolts in a given heat treatment were RW tested just a statistical significant amount of a particular heat treatment.
Don't know...I figure some of you folks might know.
Thanks...Bexar
