The ID plate from the first ballistics computer I was taught to operate and maintain in the US Navy. Note the date of manufacture, I was on this system from '84-'89.

Commonly referred to as the Mark One Able. It took 5+ people to operate and all inputs were via hand cranks. This one was on a Garcia class Destroyer Escort/Fast Frigate. https://en.wikipedia.org/wiki/Mark_I_Fire_Control_Computer
