The "Mark V" nautical sextant manufactured by Scientific Inst. Co. of Milwaukee WI (David White). is calibrated down to 1 second of arc. This is a fine precision instrument, not a replica. Has all filters and controls in place. The brass fittings and original wood handle are in excellent shape. Comes with original wooden case.
Has calibration certificate dated 1975. It is missing the small telescope but can be used without it. Captain Bligh wood have liked this one! He never heard of GPS ???
The wooden case needs some work so I am only asking $189.00 shipped!
