Greenkeyers,

The Western Electric Company keeps data sheets for many of its vacuum tubes at:
<http://www.westernelectric.com/support/we_spec_sheets.html>
The 416B specifically is 
at:<http://www.westernelectric.com/spec_sheets/416B.pdf>

Seeing the drawing makes me think that I've seen that tube in ham 
literature, likely from the 60's, and likely used in some UHF or microwave 
converter or the like.

The data sheet is dated 1953 and says:
"The 6280/416B is a planar triode designed for use as an amplifier or 
frequency multiplier at frequencies in the order of 4000 megacycles."
