[ARC5] [Milsurplus] More ARC-5 Questions - Receiver Control Box Dials

[gordon white]

     I recall seeing plastic (Bakelite?) SCR-274N control box dials 
among those I collected and gave to the Smithsonian, years ago. I have 
seen receiver & transmitter dials that looked brass-plated on the backs, 
but I think they were gold-anodized aluminum. Never saw any that were 
actual brass or copper. Those were strategic metals during WW II and I 
doubt were used for dials. Having had very early units and prototypes in 
my hands from time to time, I know all I ever saw were aluminum or plastic.
