Type "AN 11-45C-5" into Google and you will get a link to the "Handbook of operation and service instructions" for the A1 Sperry upper turret. In essence it is analog mechanical computer/ gun predictor (those skewed and slanted shapes on axles represent analog values).
Check the manual, there is a "Section II" with "dissected" parts for horisontal and vertical axes, both ballistic and prediction correction.
