Pancakes, Anyone?

Got a couple of vintage cast iron griddles at an estate sale over the weekend.  One is marked Favorite Piqua Ware - either #6 or #9 - I don't know how to read that for certain.  The other is marked 8 on the handle and has an "I" on the back.  Both probably should be re-seasoned, but I can help you with that.  These are $20 each - or $30 for the set, and I will deliver locally!
