There are no markings on the base or neck. Doesn't appear to be the usual RCA or GE or Sylvania product. One sticker says "Farnsworth Polatron", and "product of Dreyer Laboratories".

Now I gotta figure out what Farnsworth TV had a 16-inch round CRT... and are there any survivors. Otherwise the CRT will have to settle as a "conversation piece".

Fun...

How well did the tube test??

I'd be very surprised if nobody jumps on that other tube. If that's a 19DP4, someone might be able to use it in place of a 19AP4. There are a ton of 19" Dumonts out there alone.

I knew where 3 NOS 19DP4 CRTs were, and they went in a hurry... 2 went to Dumont owners, the other went to a Hoffman owner.
