[ARC5] Black radios

small parts:
   The first time I saw an automatic screw machine was at A.R.C. in 
Boonton in the 1960s. Amazing how a rather pedestrian lathe with  some 
attachments  can turn out these tiny things. Did not see an automatic 
milling machine, but I am sure they did not make those little posts 
manually. During WW II the setup process took time. Of course today they 
just dial  in  the specs on a CNC machine
