A trip down memory lane! That oven (or one almost exactly like it) was in the house I grew up in. Stove was also Thermador, but it looked different.
The oven broke, and--the repair people said--no parts existed to fix it. (These days, I know where to turn for answers...but this was years before the web, let alone AW.org.) My mother said that oven was one of the best she'd used for heat control.
