[Milsurplus] CMS Update

[Nick England]

10 tubes includes one spare 3S4 and both 3 ea. 6V6 and 3 ea. 6L6
See the equipment list at

This manual is certainly a much more professional job than the schematics
in the lid.

Hardly a big outfit - that 1950 directory lists 3 engineers, 3 technical
people, and two others.
I'm guessing that Walter Brown was just a consultant for them after he left
Brush. I just thought it was interesting to track down some of the company
history.
