I'm hoping Jeff M. (Jeb) will perhaps have some info about this range. Several years ago I saw a picture of it, and it seemed like the story mentioned it was Westinghouse. That would make sense, as it appears that the dishwasher and refrigerator in the movie are their products, as is the electric roaster. I'm thinking it mentioned the round range was in a museum in northern Ohio. I thought I remembered something about Wood County, but when I called them, they denied having such item in their collection.
I wish that the person who put this film on YouTube would have posted it in its entirety, with the opening and closing credits intact. As there was an AMC (American Movie Classics) logo present, they obviously had copied it from there. I think this film was part of a series put out by a major studio, and shown in theaters rather than a sponsored film loaned out to schools and organizations.
