Western Electric 346A & 346B Tubes Questions

[Charles Bacon]

Hi Guys,

 

I have some Western Electric 346A & 346B tubes.

 

Can anyone tell me:

 

1.      What these were used for?

 

2.      When they might have been made?

 

3.      If all 346B tubes have radium inside?

 

4.      What these are selling for today?

 

Thanks!
