Not enough information to say. In the 120, 425m was used 81 to 92. Your estimated time frame spans that. Handle construction, tang stamp, and sheath details can help narrow it down considerably. Also, depends on what you mean by a fold around sheath. A picture would be best. How many micarta spacers in the handle, 4, 3, or 2? Any symbols on the tang stamp after 120? Is the tang stamp read with the blade pointed up or down? Is the sheath flat sewn or folded? If it's a folded sheath, does the belt loop swivel? Again, pictures?
