We just happen...
to have a 1956 Chambers 24" electric oven "Cooks With the Electricity Turned Off" (better and more even baking than gas, we've had 2 Chambers gas ranges as well, and we still have 2 Chambers gas cooktops, a 27" and 42")in Copper finish (not Coppertone paint). It has the exact same insulation and construction as the gas oven models, but more even and consistent heat. We got it for our summer cottage kitchen, but kitchen design plans have changed, and we may not be needing it now.
Here's the truly ammazing thing: it is NOS, never been used! Still has the wrapping paper on the racks and drip pan inside, it is a real museum, piece. We have the manual for it as well. It was bought by some wealthy folks on a lake in Indiana near Chicago and stored in their basement for a kitchen remodel that never happened. We picked it up on the way to Denver several years ago. We're from Baltimore, so get down regularly. If of interest let me know and we can talk.
