I believe i've been the first person to have taken this out of the box since it was put in in december, nineteen fifty-one.  But I can tell you it is wrapped up and has never been unwrapped.  This is unused vintage new in the original box.

I will be listing quite a few old new stock radio parts in original boxes.  I am trying to fine all pertinent information that I can to better inform you.  But, in actuality,  you could most likely give me more information than I can find on these old parts.  Lol

Please message me if you have any questions, and thank you so much for looking at my tube.
