Jeffrod, you've found one of the ones everyone is lusting after. If you look on the inside of the right stock panel, you'll probably see the serial number stamped on it, which indicates they were fitted to this gun from the factory.
Many people don't post the full SN because they do not want the gun identified specifically; for determining the ship date for one of these, the full SN is not needed in any case.
Good luck with your decision to sell it; you've found the wrong place for encouragement to do that...
