In looking at more Griswold #7's for comps on Ebay and Etsy, I'm glad I picked up this skillet for such a great price. I'm seeing 1.5 to even 2 to 4 times the price for skillets that aren't even in as good a shape. I need to start prowling more antique stores!
And Tim-that does look very old. I can see it hanging over a fireplace with a pot of stew bubbling away. That is what I would try in it anyway.
