Well John, aside from welcoming you to the forum (Welcome!) you have found yourself a 1940's No.10 small trademark skillet with the old style handle. These are very good users and should make a much better cooking pan than your one from the other side of the earth. Griswold continued in production until the end of 1957. Other than being just about the best make of iron cookware, Griswold makes a fascinating collectible (along with most other older makes and styles of iron cookware). If you think you might want to get a few more sizes or might take an interest, pick up a copy of the "Blue Book" from your book store or the author or our president (at a discount). You can find some links to the left with thier sites starting with The Panman who authored the book. He is diligently working on a new edition of the Book of Blue right now in case you want to wait. Skillets just like yours were made in sizes 3-10 (but not a No.4 with the early handle) and a 12 which a heat ring (rim around the outside of the bottom). Griswold's skillets go larger with a 13, 14 and a 20 and smaller with a 2 and a 0, or toy, size. Be careful buying on ebay that you watch for and ASK sellers about warps, cracks and hairline cracks, pitting, etc. Good photos help a lot. And, as you have found out, shipping can't be ignored. Hopefully you will have told the shipper how to pack (tightly with good protection and padding) since iron may be tough but it is brittle. Enjoy you new pan and come back for more visits here.
