Since you have given very little information on exactly which. The website is straight forward and all you have to do is type in the serial number to your gun and BAM you are presented with the date of creation, simple as that. There is no fixed value for old 'Trade Brand Name' shotguns. Remington 700, 870 or 1100 serial/barrel number lookup will work with Remington 700, 870 or any other Remington shotgun or rifle. While it is illegal for dealers to sell guns that have been lost, stolen or used in a crime and wanted by the police, it can happen.
