WW II era US Navy- BU ships boxed sextant type stadimeter manufactured by Schick Incorporated, Stamford Conn. and dated 1944. Good working order with original adjustment tools.
This maritime instrument looks almost like a sextant, used to measure the distance in yards a ship was away from the operator of the Stadimeter. Used mostly to maintain a safe or constant distance between ships traveling in a convoy. Other uses included measuring the distance of enemy ships to determine if they were in range of guns or torpedoes. The unit was used just like a Sextant, however the operator needed to know the height, or mast height of the ship they were measuring, setting its height on the graduated arc, holding the unit just like a sextant, and viewing the top of the ship's mast through the "HORIZON MIRROR/GLASS, then turning the "DRUM SCALE", which moves the rear "INDEX MIRROR", until the ship's mast and horizon lined up together in the "HORIZON MIRROR".
The operator would then read the ship's away distance in yards. The above unit can measure a ship between 50 and 200 feet high, at a distance of 200 to 10,000 yards away. The instrument is fully functional, and in excellent original condition, made of solid blackened brass, as well as other polished brass areas with a nice aged patina.
