[Boatanchors] Chatham Electronics and A. C. Woolridge ( not Dean) Anyone?...

[WA5CAB--- via Boatanchors]

My only recollection of them is that I've seen their (Chatham) name on some 
of the W-suffix ruggedized vacuum tubes of the type where the tan base 
comes part way up the glass, specifically 807W, 0C3W and 0D3W.  So they made 
smaller tubes, too.
