I came across this Airline tube radio. It's in a gold hammertoned metal case. Built in speaker plays out the bottom. It's about size of a shoe box. AM with 2 knobs in front, some type of wire (power?) on the right and a mounting lug on the rear. Looks to me like an automotive type radio. Can't find any pics or info. Any help would be great to ID this unit.

That's cool. It does look like a car radio, I agree. I wonder if Montomery Ward sold add-on radios to be installed under dash in cars. That's really cool, and I hope someone that knows will wade in and comment. Does it work?
I have no ide on how to test it 12v? or 6v?..etc. I have included another picture of it. there is a stamping similar to the "inspected by 18" stamp which reads TES-28.

I am guessing it is designed to work on 12VDC, maybe 6VDC. I would look inside and see where the power wires went. If I could identify something that set a requirement - like knowing that the power line went directly to 12V filaments - then I would feel comfortable knowing what the input voltage was supposed to be. I expect the power line drives a vibrator which then drives a step-up transformer, rectified to produce B+. That's probably what supplies anode voltage for the tubes. But you gotta look and see. If you're not very technical, maybe there's an old-school TV repairman in your area that can help.
