This exhibit has the later logo that was introduced in 1970. The earlier pejorative term 'Foreign' has been replaced with the neutral term 'Imported' as protectionism declined.
The screen hides most of the structure. This image is looking at the triode. The heater is coiled, the cathode is flat faced.
