Before TV, it was used a lot as the video driver in various WW2 radars. The
Tung Sol data sheet issue 1 is February 1942: it was made by RCA, GE and
Tung-Sol and possibly KenRad. It was also manufactured in the DDR (Deutsche
Demokratischen Republik - Communist East Germany, prefix DM) as the 6AG& and a
6AG7k, but my German is inadequate to figure the difference.
A good tube. I seem to have quite a lot of them - need to find a use for them.

The 6AG7 was a great tube in its day. Had about the highest
transconductance of any consumer-type tube as I recall. Originally used
as a video output amplifier in early black and white TVs.
