Summary: this is a Vietnam Era Randall Model #14 and riveted sheath in excellent unused condition. The Separate S stamped blade with sawteeth is pretty much spotless (a few very light marks on the back side as shown in photo 2), the blade finish completely original. The brass guard could use a bit of cleaning, patina and a few light wipe / handling marks but that's about it. The black micarta handle has the unlined thong hole, looks brand new.
The condition of the sheath mirrors that of the knife. I carefully picked away a bit of verdigris from around the rivets, other than that it's all original. Presumably, the unused white Soft Arkansas stone in the front pouch is original to the package. Sheath condition excellent+++ or better and never carried, there is some darkness on the keeper strap and at the throat from knife storage but that’s relatively normal.
4 photos for review -- as shown, a new black canvas case included for storage. This is an incredibly nice 14 Sep S, one of the nicest I’ve seen in a long, long time. "Collector Grade" a given -- thanks and good luck.
