This is an estate sale fresh Erie No. 8 skillet with the anchor makers mark and an 8E stamp on the bottom. It was recently cooked in. The pan sits almost flat on a glass top stove, it has a very slight wobble.This is a great pan. Hat is amazing to me is how light this pan is compared to the modern pans. We cook in older Griswold pans because there is nothing like vintage cast iron. It is offered as found, estate fresh.
