Small Prismatic Stand Compass $39
The Stanley London® Prismatic Stand Compass is a reproduction of an antique small Prismatic compass mounted on a stand.
The prism allows you to simultaneously view the object being sighted and its
magnetic heading.
The hinged brass lid has a replaceable sighting thread, which 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.
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.
The brass compass card reads "T. Cooke London."
The base of the compass unscrews to expose standard 1/4-20 threads to allow mounting the compass
on a tripod.
The compass lid is 2 1/16 inches (5.2 cm) in diameter, stands 2 1/2 inches (6.4 cm)
tall, and weighs 7 1/2 ounces (215 grams).
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.
The Prismatic Stand Compass sells for only $39.
