[Milsurplus] 50s era interphone question

[WA5CAB at cs.com]

AN/AIC-3 came out in the Spring of 1945.  I was recently contacted to see 
whether I could supply some bits for the restoration of a C-47 to a slightly 
post-war configuration.  I didn't recognize them at the time but photos I 
was sent show that the aircraft carried C-166/AIC-3 Control Boxes.  What's 
confusing about the C-166, if you're only familiar with AN/AIC-2 and/or typical 
interphone systems in crew served vehicles is that there is no central 
amplifier.  Each C-166 includes an amplifier for that station.  And the things 
have so many controls on them that you might think the C-166 was a central 
distribution box of some sort.

However, in some installations (details of why not specified in the AN) 
there was an AM-26/AIC as well.
