18 attack survival age

I came across a model 18 7 1/2"
Johnson rough back
brass cap and the compass has a cover? marked japan
"supposedly" went to vietnam
looks like it has a story to tell, but I don't know it.
any way to tell when it was made?

George, It is a post 1972 knife for sure since the sheath is unriveted. I would guess a bit later possibly early 80's but it's difficult to be certain from just photos.

right on, I grabbed a few and they are mostly in that time period
