[Boatanchors] 416B threads ... was RE: SI units and the rest

[Kludge]

Whoa, three in one ... :-)

Thanks for the info.  I don't remember meeting a 416B up close and personal
when I was playing up on 30cm & up but I do remember a few articles about
it.  Always seemed like a fun tube to play with.

Best regards,
