Joe H. Here's one for you. I had a friend give me a mint 110 that doesn't have any markings or stampings on it! Friend was an US Army Ranger in the '80's and was given the knife by an old VN vet Ranger Sgt.when he was in the service. The sheath is black ,has Buck logo on the snap and has seen hard service but the knife is almost mint and appears unsharpened. It has brass and ss pins,dark wood and the chunky look of older (60's-70's) 110's. I've seen enough 110's both old and new to say this is the real thing (ie Buck) or the best copy ever made-but not one marking or logo on it. I saw several 110's in VN as they were popular with SF types but were private purchase with Buck logos. Any "clandestine" 110's ever made during VN for SF issue? Weldonia
