I don't see a model number on it but one man wrote regarding the chassis number 6T41Z that corresponds to a model number Y600L from 1956 to 1959. Those years also correspond well to the last patent from a list posted inside the radio, number 2,709,301 that was issued in 1955. The other bands hum or have a static sound as I don't think anyone is broadcasting. One band, I think it was the 2-4MC had what sounded like a repeating pattern of beeps a little like the dots (no dashes) of Morse code around the 2.4 mark on the dial. I doubt that's what is was but mention it by way of description.
See my condition description above too. I mentioned that the round knob sticks (slips) after moving a little.
I can move the needle some but then it will stop. I can open up the back and move the needle across the entire range of the band with small pliers on the wire that controls it (moves freely) but I think the knob needs to be secured more tightly. I did not want to try to do this by removing the knob and using super glue as someone else may have a replacement or want to secure it more another way, perhaps a thin plastic shim in the hole of the knob would work. I would think it could be replaced. I think someone who knows how could fix these 2 problems rather quickly.
The leather case, considering the age is in nice condition with a few minor scuffs and small spots. I was surprised that the speaker has some nice bass sound to it.
