Think I'm likely to find "S-Unit" if I look hard enough?

Hi Roy,

One could see stars in the middle of the day if they squint their eyes
hard enough. Seems to me Collins literature covered S Units
adequately and they were certainly the Cadillac of the pro's.
Hammerlund is another probable source. National another. RCA as
early as 1941.

On the other hand, I certainly wouldn't waste my eyes scanning the
shelves of the engineering library.
