Don't second guess. It is indeed a Buck sheath, none of those had the Buck snap. Buck's Classic series came with those handsome tooled sheaths from around 81-82 (3 dot era) to 87. By then the series was winding down. I have the knives and sheaths of that series and when displayed folks really stop and stare at them. Then ask, "did Buck make those?" Yours is a correct sheath. DM
