[Boatanchors] Tube questions

[telegrapher at att.net]

Does anyone remember what piece of gear, ham i suspect, that the 902A crt was part of?  I have a couple of them, one at least is a NIB item, and would like for someone that could use them to contact me off the list.  What was the CRT that was used in the 200V.  Don't remember if the 100V had a crt display or not?  How about the small Millen scope?  Can't see throwing these things away.

2ndly, what amp used the 3-400Z tubes?  I've got a pair of them that look new, filaments check good but that's all i know about them.  What kind of value would they have?

If there is another list where i can get more detail or should ask this question, please advise.

Thanks
