So I picked up this piece this weekend it was in pretty rough shape but the price was right, after cleaning it up it has a 4 on the handle and X O on the underside of the handle. It has an inset Heat Ring - I have set it next to a few #4's that I had and the only one it matched up with size wise was a Griswold Large Block #4 - it was smaller than the No Notch Lodge #4 and barely larger than my No Notch Lodge #3 I was wondering if anyone had any ideas about this one aside from UFO (Unidentified Frying Object)
