I have a couple of questions that I'm hoping you guys could help me out with. I picked up an older buck 110 with the .Buck.. tang stamp. I think that dates it to like the late seventies or early eighties right? Anyway, the plot thinkens. As I was cleaning it up I noticed that in a faint (nonprofessional) scrawl on flat of the backspring is etched "Paoln 05-163-330" Im trying to figure it out, it doesnt seem like a social security number, could it be a military id # or something like that? Anyone care to venture a guess on this one?
