"U.S. NAVAL SEXTANT TYPE STADIMETER"

An original U.S Naval Sextant Type Stadimeter.
This device looking almost exactly like a sextant was 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 unit is fully functional, and in excellent original condition, made of
solid ebonized brass, as well as other polished brass areas with
a nice aged patina.
The unit has original tags on both the box and Stadimeter that states:
