Man, has it changed in our field! Used to be you could get functional parts for 15 - 20 years or more. In fact, I remember finding a few parts for customers for 30 year old units. In the early 1990's, I chased down a clock-timer for a 1962 Tappan 'Fabulous 400' stove in England - this thing was nuts. Sat on either a metal cabinet with doors or your own cabinets. Had a side-by-side double oven on top at eye level and a pull out cooktop drawer for the burners. I even located a bake burner for a 1959 oven for a woman in Scotland around that same time! The factory actually had one sitting in a storage room and someone was good enough to dig for me and found it. No way you'll find that stuff today. Everybody throws things out.
