I've only been able to find one other example of this MASSIVE #16 skillet on line. I bought this skillet already seasoned, but I would suggest heating it and wiping it down a few times before use. There is minor pitting in a few places around the inside surface, but is mostly smooth. The only mark on the bottom is a H, which is a Mold mark. Diameter around top is 15 7/8.The item "#16 Cast Iron Skillet, Seasoned, Raised #, Sits Flat, Rare" is in sale since Wednesday, May 10, 2017.
