I recently bought a pilot survival knife-polished blade, pommel, and guard. No dates on pommel or guard, blade marked "Camillus, New York U.S.A. " Box is wood-grained -end says "Camillus has the edge" along with co. name and address. I assume this is a civilian version of the Camillus pilot survival knife. Any info on dates of manufacture for this knife or other info would be appreciated. I bought the knife to use not as a collectable so my interest is just curiosity-my other Camillus knives are of the boy scout variety...It is a real nice knife.
