Kabar Stag Folding Hunter Questions

[Drscotty]

I picked up two Kabar folding hunters with stag handles today. One was obviously never used. The other looks like it was not used much at all. My question is about dating them. The research that I have come across as far as tang stamps seems incomplete. Would anyone mind trying to give me an idea of when these were produced?

The first one is older, 1952-1969. The one with the model number was made after 1968. I don't pay attention to when the post 1968 knives were made since I don't collect them. Definitely handsome knives!
