[Milsurplus] WW II Tx Tube ???

[J. Forster]

I'm pretty sure the unit I'm remembering was airborn, so it would not have been an
interrogator. It was all Aluminum and had no plug in modules. As I remember, it was
about 12" high x 15" wide x 10" deep and the tubes were behind a door in front. The
coax were outside the box, maybe, and were about 5/8" OD. Don't think there was much
else in the box, but it's been 40+ years.
