Thanks Peter, that certainly is a much more accurate account to the story of them I have heard and read about in the past. I remember now a discussion about them in years past with examples having been brought forth with mid production serial numbers, sort of clouding the early only suggestion. I would wager a guess to the early "cash and carry" examples being legitimate non US PROPERTY marked examples where as the later ones could certainly be as Mr. Breakey suggests... a random example of s**t happens.
