I'm not sure. He just missed WWII, but went on I think two tours to Vietnam. I'll have to ask him again if this was his gun at that time or not. Probably was acquired some time after Vietnam. I wish I knew the history of these pieces better, but I tend to try and avoid bothering him with all my questions when I go to see him. Also, I don't know how comfortable he is with talking about his duty time because everything I know about what he ever did I had to find out by asking him directly just a few months ago. Not like all the grand kids got to sit around and here war stories all the time or anything you know?
