@kenshirriff it’s aerospace and It looks military. But I’m fairly sure that it’s not navigation. Military aircraft from the 50’s would either use TACAN, a beacon system or INS which means it would need to be hooked up to a gyroscope.
It could be part of an early form of computer bombing system for some kind of primitive CCRP release system. But even then it’s missing things that a bomb system would have like inputs for measurements like drag factors on bomb types.
Things like T/A (Target Angle), and G/T (Ground Target?) make it look like it was at least part of some kind of targeting system.
