[ARC5] [Milsurplus] Old surplus catalogs are always fun to look through

I always wanted to get one of these sets out of curiosity.

The sets are quite large. How did they install 4 systems in the atomic bombs? This they use FURE complete systems or did they use four front end systems to a common IF and voter system?
