My opinion.... Oh boy, here goes.
Papers are crap.
how many people have a printer?
Seriously, I would be more concerned if it DID have papers. Think about it... Papers bring big coin right? Then papers would be motivation for faking.... All there is to it.
My second point is this. To date, not a single NON /26\ has been verified with no import mark that hasn't been suspect of grinding, paint, missing rear cover etc. I mention the cover because century had an early import mark that was on the cover which can easily be swapped out, so stay away from one with a mismatch or blank cover. That being said, if what people claim to be true is accurate, that 'guns missed the import stamp all the time' were true. Then why are they ONLY /26\ guns!?!? /26\ represents MAYBE 10% of the guns imported, so where are all the NON /26\ guns with no import stamp?!?! Think about it... If this were true, we should be seeing MANY times more non /26\ guns not having a stamp. But nooooooo not a single darn one!
You add all that to the simple fact we DO NOT have any verified non /26\ gun to have come out of Nam..... Do the math.
Keep in mind, nobody pays big coin for one. Maybe 100 to 150 over current standard value.
