I've never owned a model 50 in any variety but my uncle did years ago, in the 1960s or 70s. He told me that the performance was less then thrilling, even so far as a 5 tube TRF sets go, that may explain why they don't turn up that much. Even back then they used to publish reviews of the latest radio models, so if one was lackluster it's likely that people would have passed it over in favor of the next model up or switched to a similar model of a different brand that performed better, like a Crosley. Many that were bought were probably dumped later for similar reasons rather then keeping them in service. I don't know how much of an issue the transformer was, since it was only a five tuber maybe they figured it would not have to work too hard? At least this example has a nice looking cabinet and is in good cosmetic condition.
