Yes, that sheath was special to the Sears American Eagle series, which included a bowie knife, the 165, and a folding hunter (25OT variant). And there was a 41OT variant of a bird and trout knife but I don't think that one had that type of sheath. The other three did. I believe the sheath contractor was in southern California. At one time I could remember the name, but when I searched the internet there was no longer any trace of that company. The sheaths are of an unusual design and are very stiff compared to most. Very nice example that you are showing. Thanks! There was another variant of the 165 sold by Sears also. It had a hidden tang and a brass buttplate like the 49'r series knives. Come to think of it, I am putting one of those up for sale tonight..er... someplace.
