Kingcreek,
No your story is not lame or B.S., but an interesting topic to post. and it has generated some good comments. Thank you for stimulating our grey matter.
Being "sterile" has many connotations. They range from not wanting a casual observer to know whether a combat infantryman is from the 8th Infantry Division or the 3d Armored
Division all the way up to a "plausable deniability", that so-and-so is not a citizen, agent or operative of this country and is not working on behalf of this country. Plausable deniablitity usually winds up being a political charade and is practiced rigorously at the pointed end of the spear but is joked about at the top. For example, the cross border operations run in viet nam by MACV employed troops who mostly had a special forces background. When they went "over the fence" they were still large hairy americans carrying american equipment except for the most casual of personal items, (cameras, pocketknives, handguns, compasses, etc). They were still carrying CAR-15's, M-26 frags and being delivered by american made helicopters and being supported by the u.s. air force. But when they went on a cross border mission, they were rigorous is leaving behind any incriminating personal items. There was no attempt to fool the north vietnamese into thinking they were fighting canadian or finnish peace keeping forces. Rather there was wiggle room at the negotiating table at the peace talks to deny that these were in fact americans.
Being a bartender for years, I cant tell you how many CIA agents and MAC-SOG commandos I've encountered and how many implausabe BS war stories I've heard. I oughtta write a book someday. It got to the point where I took down the flag, the case with some BS service medals in it, and the pictures of my tired and dirty mates out in the bush These items inspired far too many war strories.
I have always been a believer in Occam's Razor. That is, the shortest and least complicated story that fits the facts is usually the truest. My money is on this gun being butchered by an amateur gun plumber. Having said that, a good story should be judged more on how good the story is rather than how true it is.
