I've never seen a single door model with freezer on the bottom. It must be a rare one, and except for that one glass shelf is complete and very clean inside.
From the seller's description, it sounds like defrosting might be easier than average on this one.
I wonder if some rubbing compound might be enough to restore the finish on the door.
To bad the exterior doesn't do the interior justice. Inside looks to be in decent shape. First time I've seen the freezer in the bottom of a single door frig.
If you notice, there is a coldplate in the top of the refrigerator (keeping the upper part cool) so the freezer can be either top or bottom...Frigidaire was the only other one I know of with a bottom-freezer in a single door.
