Greetings all, here's my new guy post - early 60's model 5-8 w/ compass. Brown Button sheath is marked 1 8 in the butterfly, two toned gray stone. I'm told by the person I bought this from that the owner carried it in RVN in '66 with the 101st - still working on some documentation on that so right now it's just a cool old knife instead of a really cool old knife.
Any other input from the experts would be appreciated.

I'll have to work on the photo skills, these are just with an IPAD out on the deck.
I've been following the forums for a while now - wanted to throw a quick shout out to all the other prior service guys on here (22 yrs Army).
