I would look for a GE P-7 Self-Cleaning Electric oven from 1966- the early 1980s if you actually want to use it, otherwise get a vintage gas oven and leave the gas turned off as these older gas ovens pilot lights are nasty smelling and produce a lot of carbon monoxide even when not in use.
For a while in the 1980s, Thermador offered 24" wall ovens also; probably rare as hen's teeth, but they are a possibility. I would imagine that a gas oven from the time period you want, if ever connected to gas, would be a pretty rusted mess by now unless it was a match-lit model--always loved that WHUMP at ignition.
Sears took care to offer 24-inchers for quite some time - they were interested in hanging on to customers looking to replace that size. Roper, who made many of Sears' units, also offered 24-inch models at least up into the '80s.
Yes I forgot to mention Thermador Thanks Tom, they offered a great Self-Cleaning 24" oven from about 1966 on into the early 1990s, the neat thing about these TD SC Os was that they had a built in exhaust blower and you vented them out of the house like a clothes dryer so there was almost no hot smokey smell when baking or broiling or cleaning.
They were built in a era when people actually cooked everyday, cooking appliances today have really taken a turn for the worst as many great features are no longer offered such as, automatically temperature controlled top burners on gas and electric ranges, no rotisseries in ovens, ovens have gotten too large today and take too long to preheat and use much more energy, they also do not do as good a job on self-cleaning as they once did.
Sears wall ovens were mostly built by Roper in the 1960s and into the 1980s, Sears cooking appliances were so-so, generally Sears cooking appliances along with their D&M built DWs were weak lines and few few serious appliance shoppers ever bought either.
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.
My aunt has a 24" Kitchen-Aid, built by Chambers range from 1990+/- which replaced an older gas wall oven and she loves it, so that might be something to look for.
Electric.
Sears sold one just like it with the Kenmore name.
Mine still "mostly" works - the digital clock/timer/control center display goes on and off and I have to bang on the side of the control panel to make it come back on.
The control knob for the digital settings is also "wonky" and it's VERY hard to set the time or temperature as it makes the numbers jump all over the place instead of "in order" like they should.
I once looked at getting the digital control replaced (from Sears service) and they quoted a price of over $600!
Also, the oven vent for the upper oven is stupidly located right under the knob for the lower oven.
When cooking "steamy" things, the knob gets all wet.
I take the knob off during the cleaning cycle as the heat discolors it (I've already replaced it twice now...)
I looked into getting a new 24" oven a year or two ago and the choices are few - KitchenAid, GE and Maytag were the only ones that would fit without cabinet modifications. I think Sears had one "Kenmore" model which looked like the GE to me.
Bill, your description of your wall oven's quirks is too funny. Love the "percussive" method of making the control come back to life and your explaining about the wet knob. I am glad I did not read it at work, because I was howling and bent double with laughter.
Is very much in business, they are the ONLY family owned stove manufacturer left in the US, in addition to the Brown stoves they also make the high end Five Star brand,They are still in an old run down looking factory in Cleveland Tennessee, I have been there and seen it!
