I have done the GB research and looked on the Colt Forum and have come up some what empty. Just got back from the LGS and they have a Diamondback 6" blue .22. I have very little experience with 100% guns (mostly 95-98%) but this one is truly 100% not even a turn line. Still has factory grease/oil. Serial nbr is S837xx. Numbered and authentic box. The red tape that holds the plastic bag has not been broken and the bag is still closed so I assume all paper work is there. Only negative is there are 2 places on the box where clear tape has been used for repairs. So would this be called a NIB? And what value would the DB experts place on it. They are holding it for me now.
