I agree, pictures will help with getting a good answer. There is testimony out there that Western did repair some WW2 knives sent into them by the owners and got the original handle replaced with wood.
Does the blade have the "L46" stamped on it?
Also when Coleman owned Western, they didn't hold strictly to the original intent of the stock number. Lots of examples of knives with stock numbers that should indicate a specific handle material that were sold with a different type handle.
