I have seen quite a few of these in this locale. Like the contractors put these in a lot of kitchens. Even some without a window, but all Westinghouse. Unfortunately, many have disappeared due to remodeling. But that hasn't been too many years ago-these ovens seem to last forever. A friend of mine had one in yellow.
This is very cool, we had a similar Westinghouse in a house built in the early 60's, the controls were on the side of the oven. Our was 30" wide, this one is 33 inches wide - say hello to a custom carpenter and a home equity line of credit ;-)
