Sunbeam square frying pan
I have the exact same one as you have. My mother got it, I think, with trading stamps in the early 60's. Your previous post about the pork chops brought a laugh. My mother would put her pork chops in the Sunbeam for a couple hours until they were dried right out and tough as shoe leather. She was so afraid if the food was not cooked way beyond completion, you would get sick from it.
