Re: Unleash The Clockworks Of War!
Well, yeah.. I mean, the single easiest way they could have convinced my 16 year old self to study Trig would have been to mention that it was essential to historical gunnery.
That said, I'm actually half recalling systems from the latter portion of the 19th Century, around about the turn of the century that I stumbled across whilst doing some research a few years back for some Space 1889 to Hero conversion stuff. It know it was back when I was looking hard at Hotchkiss revolving cannons and Nordenfeldt guns, to fix the time a bit.
As I recall it was an early attempt to build basically a self adjusting gun mount, so you could target optically and click in your range estimate and the gun would set its own elevation and adjust for wind.
OH, here's a fun link, just cause... http://www.navyandmarine.org/ondeck/1880DisappearingGuns.htm
