Ever seen a vacuum tube this big?

[betterthan]

I don't have much in the way of old vacuum tube equipment as I stick to solid state Pioneer stuff...but I was given this old Westinghouse vacuum tube recently and figured it would be a point of interest for someone here.

I have absolutely no use for it, so I will probably figure out how to work it in as a decoration for the living room...I think it was used for WWII era radar equipment originally.
