No, it's not worth 3 grand, but it is worth more than scrap. The stove is iconic in that it was the first straightline design for Westinghouse. They were a year behind GE and Frigidaire in squaring off their porcelain coated appliances. New porcelaining techniques and formulas emabled porcelain to cope with the stresses of squared-off corners instead of the rounded ones needed previously and the V-shaped control panel would be echoed in the Frididaire laundry apliances beginning a couple of years later. It is also the first Westinghouse range with the wide master oven and full height narrow companion oven which is an interesting term for the small oven. The seller calls it a bread oven. The word companion comes from the Latin "cum" = with and "pan" = bread meaning one with whom you share bread, a friend of sorts. Actually in previous years, the wide oven would have been the bread oven when the weekly or twice weekly bread baking took place. I always thought it so unfortunate that ovens grew in size just when heavy baking became less necessary in households. This range still has lighted controls with different colors for each heat and, like so many WH ranges, when you rotated a surface unit switch out of the OFF position the full width fluorescent light came on and we all know fluorescent lights seemed to bring appliances to life, like they woke up in your presence or at your touch. It is also the model for the Westinghouse recipe box often seen on ebay. This was the year their deepwell disappeared and their 40" ranges went to a divided cooktop. So there's lots of neat stuff about the range, but not $3000.00 worth.
In the 70s sometime, I went into a second hand store in Decatur and found about 5 1957 TOL Westinghouse 40" ranges. It looked like a small apartment house had changed them out because I could not figure how else this many identical ranges in pretty good shape would appear unless from a school, maybe. I wanted one so bad, but had nowhere to put it. Brenda Bendix, my Duomatic was all bundled up & living under my parent's basement stairs and seemed to be a real thorn in their sides and I did not have money to get a truck to have it moved since I was still in school, I think. When I got my first house, my brother and his partner came up that first summer and two things my parents sent in the van were the piano and the Bendix.
