Hi Kevin, I just thought I'd let you know that I have a Setchell Carlson TV that looks exactly like your model 15, but mine doesn't have a model number on it. It looks like the model number was obliterated at the factory. As you can see, mine is missing some knobs and the long narrow cover over the front controls. It also has a wooden stand that, if I remember right, matches the TV (these are in storage so I can't see the stand right now).
