How do you find the grade on a Remington 1100 shotgun?

I'm not 1100 expert BUT I put this article up on the site and it might have the answers if not head over to the forums someone there will probably be able to help you.

On the Remington Society of America on the home page there is a other on-line article links, the 4th quarter of 2006 there is a collecting model 1100 shotguns article.
