I see that the butt is attached with a pin. Maybe Tommy Bish?
This knife appears a bit later than when Bish was working on knives. He was done probably around the late 70's. The blade and hilt appear to be 80's-90's anyway.
I think the sheath stamp orientation is a non issue. There were some questions as to whether it was a Byrd copy, and they can be tough to spot, with many passing as original Johnson's.
I wasn't at Blade to see this knife, but the several folks I spoke to that did see it alluded to a re-handle. None thought it was done by Leschorn, White, or Bish. FB would be capable of doing it, and IF it was one of his sheaths, that would pretty much confirm it.
One thing you have to consider, those three guys that did Randall work outside the shop generally worked on smaller blades, with the only full tang model i know of being a 15 that Leschorn worked on. Leschorn did do some Bear Bowies, and Bish did some full sized knives like 1-8 & 2-8, but other than the 15 I know of, no other full tang models, even as a CDT version of that model.
The black & brass spacer arrangement would be uncommon for the early to mid-80's, not impossible, but uncommon, and is a real departure from what one would expect to see from Leschorn, White, oe Bish and their "trademark" spacer arrangements.
Again, I didn't see it, so going on what others told me with no official opinion w/o seeing it in hand.
