I've been looking for one of these for a long while now, and finally was able to find one over the weekend. I brought it home and shined it up and it works great.
That's just like the first Amana that Mom and Dad bought; I remember it well. Those things seem to be huge inside. Maybe it is the shiny inner surfaces that help make it appear to be so big. I remember thinking it felt like overkill heating up a single pastry in such a massive device. But of course I did it anyway because it was fun.
