Retro/Vintage Westinghouse Covered Loaf Pan/Casserole This is a fully marked retro/vintage heavy duty covered baking dish put out by Westinghouse Company, in the 40's, when your wife got her new electric stove. Both the domed lid, in clear glass, with built in top handle, is marked with a underlined W and the milk glass base with a large underlined W. Westinghouse knows housewives and they knew that they needed some side handles on the base so it could be moved in and out of the oven with ease. This covered loaf pan measures 9 1/8" in length, including the built in handles, and is 5 1/8" in width. Enjoy!!
