[Milsurplus] Korea-era IFF fits BC-455 rack

[Unserviceable but Repairable]

The B-57 Cambera, at least, used an IFF called a APW-11/RT-122B
that goes in a command rx parking place... right down to rear connector

But to prevent accidental plug-in, there were 2 spears in rear so
it'd only go in it's reserved parking place

But was surprised to see ARC-5/274N radio nests were still spec'd into 50s

BTW, the APW-11 is packaging triumph (mga?)  Some ten 7&9 pin miniatures & 
a lighthouse tube in that restricted real estate

And this APW-11 emerged from a country flea market.  If these things could
only talk
