Very nice hard to find early antique Griswold cast iron No 13 iron skillet frying pan with smoke ring and large block logo. Marked "Cast Iron Skillet 13 Erie, PA., U.S.A. 720" on bottom with Griswold block logo in center and "13" on top handle. Good condition, no breaks or repairs, smooth casting inside and out, dark patina, a few scratches on bottom (see photos). This may be something that might clean off? It has some type of coating that makes it really shiny and shows off the polish...ed inside. I have no idea if my father purchased it this way or if it was something he had put on it. A very slight rock when sitting flat, nothing major at all. This old iron skillet would display well with your Griswold or cast iron cookware collection. We guarantee all items as described but please feel free to ask any questions. Buyer to pay shipping and payment due within two days from end of auction. Thank you for viewing our auctions and be sure to watch for other cast iron cookware that will be listed weekly.
