An early Astro with no handle slabs has come online that might be an early one. It has a canteen snap type safety keeper. I don't think I have seen one in this early a sheath.
I'm not qualified to say for sure, but wasn't this kind of sheath replaced by the brown button sometime in the 1960s?
Any thoughts when it was made?
I haven't seen this knife posted here and I know this community is interested in the older knives so thought it appropriate.
Thank You.
