Like Crutchtip, with his authentications, I don't value or appraise without first having the knife & sheath in hand..."but"...with no photos of the back of the sheath or stone, I recon a Heiser sheath...only because Smittys were not made earlier. The stone pocket has an early look to it, i.e. Clarence Moore. Is the back stamped Heiser?
Nice knife,
