British Prismatic Pocket Compass in Antique Finish
This is a heavy solid brass air-damped reproduction of a Mark III handheld British Prismatic Military Marching Compass.
This
Solid Brass Engineering Lensatic Compass is available in a polished
brass finish. The compass card has the standard 0 - 360 degree scale, as
well as the 0 - 64 Mil scale (one yard at 1,000 yards).
The
lid opens and the front prismatic sight folds over the compass to
function as the front sight. The prism has a magnifier to allow viewing
the compass card and the object being sighted simultaneously.
The
height of the front prismatic sight can be adjusted to focus the
compass card. The lid has a scribed line in a glass window to serve as
the rear sight, and the glass is protected by an exterior guard. A brass
bezel can be rotated and is marked off in 10-degree increments. The
bezel has detents so you can change the heading reference a known amount
without looking at the compass. A side adjustment varies the tension on
the detent mechanism. The outside diameter of the compass case is
engraved with a compass rose for fast determination of rough direction.
The
compass has a antique finish and the compass measures 2 3/8 inches (6.0
cm) in diameter, 1 1/4 inches (3.2 cm) thick, and weighs a very solid
300 grams). This compass is fully functional, but is not certified
accurate.
