This might interest someone.

The description of how it was obtained is interesting.

"I got this from a scrap yard. The folks there save vacuum tubes for me and when they saw "tube" on 
this they pulled it out of the test set. I don't see any cut wires so it looks like they unhooked it. 
It is about 15 by 5 1/2 inches. "

I'd hate to guess the value of the item they destroyed to pull the "tube" for him!!
