Set of Two Solid Brass Prismatic STALLONE-INDIA Compasses

Set of Two Solid Brass Prismatic STALLONE-INDIA
Compasses: This set consists of the following two solid brass compasses:

A – 3” solid brass prismatic compass
mounted on brass stand. This Compass is a reproduction of an antique Prismatic
compass on a stand. The prism allows you to simultaneously view the
object being sighted and its magnetic heading. The hinged brass lid flips
up to expose the compass. The prism is also hinged and can be rotated up
for use as a front sight, and to view the compass heading without averting the
user's gaze. Reverse mirror image printing on the compass rose reads properly
when viewed though the prism with half-degree resolution. When making a
heading measurement, the magnetic heading appears under the object being
sighted. Adjustment screws allow the height of the prism to be precisely
set. The compass has a needle lift mechanism that is operated with a
thumbscrew on the bottom of the compass, to protect the compass jewel when
being transported. A small in the rear of the compass activates a
needle freeze mechanism to hold a compass heading for easier reading. The
base of the compass unscrews to expose standard ¼ - *0 threads to allow
mounting the compass on a tripod. Its stands 3 ½ inches (8.9 cm)
tall. This compass is beautifully crafted from solid brass, and polished
to a mirror-like shine. The built-in stand makes this Prismatic Compass a
perfect desk accessory.
