most outer scale : real (mast)height for range, or real (ship)length for AOB

outer scale of moveable wheel: range only (number times 100 meters)

inside scale of moveable wheel: optical height or (halve?) length as observed in the scope.

most inner scale: AOB scale, 90 degrees is index to which observed height should be aligned for range measurement in 6x zoom.
