The product is a vintage Griswold "Erie" No. 10 skillet, restored to sit flat and smoke ring. This cast iron skillet is compatible with gas and electric stoves, and features a non-stick surface coating. It is a part of the Third Series, with a round shape and black color. Additionally, it is oven-safe and a collectible piece from the late 19th century, making it a valuable addition to any kitchen or cookware collection.I believe this is the 1st series.
