I found a very large United Electronics 805 tube recently at an estate sale. (In good shape). I’m trying to identity and date it.
I understand these United tubes are USA-made WWII era. Is there any way to find out the year and place of production?

Thx…good info!
Here’s a pic of my tube. Only markings are “805” on metal base and glass and “9C-3785” hand written below the grey plates. (Could be TC-3785”). Mean anything???
