For your consideration is this vintage unmarked cast iron Square Skillet from Wagner Ware.
Unmarked Wagner square cast iron skillet. Manufactured post 1960. This model is commonly referred to as the 1218.
It measures 9 1/2 inches wide (edge to edge in both directions) and 1 7/8 inches tall. Weighs in at 4 pounds 1 ounces. No cracks.
It has been stripped clean and seasoned with two coats. The exterior surface is excellent with crisp, clear lettering. The interior cooking surface is nice and smooth with typical marks from age and use.
See photos for best description. If the post is up, it is available.
