Greg, Congratulations on your beautiful new stove. I would protect the floor of that oven with foil or one of those heavy foil oven protectors that are sold with the disposable foil bake ware under the bake element before using it; just keep foil away from the receptacle for the bake element. I am not sure about this, but I think that silicone mats are sold for oven floors now also. They also come in a size for the bottom of a toaster oven also and can be cut to fit.
After one of the newspaper stories about out collection, a nice young couple called us about a stove they had in their basement. It was original to the house and although they remodeled the kitchen, they saved the stove down in the dry basement because they knew it was too nice to junk. It was in beautiful shape. It is like yours, but with a double oven and maybe an 8 inch rear element instead of the deep well. Our next door neighbor for a few years in the 50s had your single oven version, Greg, and it was the memory of that stove that made finding one like it one of my goals.
Greg, do both of the sections of the element heat on "3" and "warm"? If they do, it is not a broken wire, but the switch. On "3" both elements are in parallel on 110-120 and on warm, they are both in series on 110-120. High is 1600 watts on 250 volts, 1425 on 220. The other wattages at 250 volts are 640 watts on "2" when the inner coil is heated at 250 volts, 400 watts on "3" because the voltage is dropped from 250 to 110-120, Low is 160 watts which is 1/4 of 640, so the inner coil is switched to 110-120 on Low and Warm is 100 watts. I hope that you have a lot of fun with this range. It is a treasure.
What a neat radiator in the kitchen. A family friend used to put a folded towel on the dining room radiator and let the dough for the Parker House Rolls rise there, covered with a dish towel of course. Then after the meal, coffee was brewed in the glass Cory to go with dessert, usually her wonderful pound cake. They would actually let a 7 year old me stir the coffee in the top bowl! Later, while the adults talked, I would ask to be excused and walk down to the laundry room in their garden apartment complex. There was an old round Bendix and a 1956 GE washer. The Bendix had a red wavy line about 1/3 of the way up the glass and under it the words "suds level." For any of you who lived in the Decatur area, these were the brick apartments on Clairemont, just north of North Decatur Road. The whole thing was torn down to make way for high density development in the 90s, I think.
