General Electric VT4C or 211 Tubes

Well this looks like trouble. 

What could one do with six 211 tubes?

 Date codes say 1942.

If this was in a Godzilla film it would be MonstroTriode or TriodeZilla.

  

 Very rugged and amazing construction.

 To be honest I'm not exactly sure what we will do with these but they are from my friends Chris's collection. He has had an idea in his head for these for many years. Going to be an interesting and fun adventure. I'm definitely over my head here so it is a good thing I'll have professional help.
