Does it look like this one?
I'm a fan of the early DuMont sets that use an Inputuner and provide integrated FM radio. Not many companies did that. Am I right in guessing this is an original Andrea design, rather than a DuMont clone? That would make it somewhat unusual, at least in my book.
With a 16" CRT, that must be one hefty tabletop!
