In the pic with the oven door open, notice two things: the little hole at the top of each door is the oven vent and the thoughtfully included pan at the bottom of the oven cavity to prevent spills from running out. A school friend had a disaster with a cake running out of a tube pan and leaking into the drawers beneath a GE builtin oven. While this is also because this model has the "Miracle Oven" where you could remove that pan and bake element and position it on a set of rack guides then plug the element in the middle of the oven (see the white porcelain terminal block) to give two half size ovens (a second bake element was under the pan), it made cleaning a wall oven much easier and was also included in the single ovens. Do you see that slot at the front of the pan? There was a little flat piece of metal with a bent over hook at the top that hung from that slot and formed a door for the lower of the two ovens so that A, you could use the ovens at two different temperatures and B, the main doors could be open if you wanted to broil in the upper part of the cavity while baking in the lower. That stainless steel strip above the doors is stuck. It should glide out when the doors are opened. It is the front of a heat shield for the clock because it had a plastic "crystal?" on the front of it and of course the clock knobs were plastic also. The 2 thermostat knobs were Bakelite so they would stand the heat.
John and I found the single oven like this and matching cooktop in stainless steel in a pathetic thrift store in Decatur when we were on an appliance run to my parents in the early 80s. I think I paid less than $10 for the oven. With a little clean up it worked great and sat on top of the counter over the KDS14 in my house in Greenbelt. This wall oven is the same size inside as the 40" range master oven of the period and holds an unbelievable amount of food. It has a 3000 watt open coil broiler that is really powerful, fast and even-heating. It bakes beautifully also with a trusty Wilcolator thermostat.
