I picked up a Hallicrafters 514 portable TV. Unfortunately I am missing the back of the set. I was wondering if the back was the same as the 505/506 model. Or was it different (like it had feet to rest the set on when you put it down). Someone on the Antique Radios forum said it may have had rubber feet on it. Does anyone have one of these that they can take a picture of the back for me? Thanks!
