optical rangefinders used on WWII battle ships

Postby history buff on Sun May 01, 2005 5:44 pm

I have seen rangefinders in the turrets of battleships that had a base line of at least 20 feet. Could someone make a similar one with say a baseline of 4 ft. using parts from old binoculars, PVC pipe, etc.
Could you make a diagram of how to articulate the moveable portions and calibrations?
