Military and Naval Mechanical Analog Computers

I’ve been interested in this topic since I used Navy mechanical-analog computers to put “rounds on target” in Vietnam in the early 1970’s. I’ve collected a few small versions of those devices, all of which are German and are what I call “static-solution” machines in that the parts move only when making inputs of the various parameters, then stop. Those are for field artillery in two examples, and machine guns in another. They are for fixed targets and don’t keep a “running solution” as did WWII-era Army and Navy computers designed to solve for moving targets.
