The #10 Griswold Cast Iron Griddle 12×24 with a large logo is a vintage collectible piece that does not wobble. This skillet/griddle is made of sturdy cast iron and has a gas stove compatibility. With its black color and antique charm, this item is a must-have for any collector or home cook looking to add a touch of nostalgia to their kitchen. The Griswold brand is known for its quality cookware, making this piece a valuable addition to any kitchen collection. I cleaned and seasoned as good as I could, but I do not have an oven big enough to properly heat this for resto and my grill just woudn’t get hot it enough. It sits flat and was tested on a sheet of glass. Some pitting (should be visible in last photo) but no breaks, repairs or unusual damage. Ghost mark appears below the 747 and looks like(A 3210) Tried to get pics outside and in, with flash and without if you want something retaken or have questions let me know.
