I have a Chamber 12B that my grandparents bought in May, 1941..
I bought the house from their estate about 30 years ago, and opted to keep the stove.. The thing is heavy... like really heavy.... the whole top is cast iron.. Also the stove is really well insulated (mineral wool... probably asbestos too)
Note, that compared to modern appliances the oven is quite small.. So doing thanksgiving with a bunch of sides is an exercise in logistics..
Its built like a tank, and there is still parts and service availability.. (at least near me)
