This Stanley London® compass is a heavy solid brass reproduction of an antique stand surveying
compass.
The compass is mounted on a stand with three independently adjustable feet and the compass is free to rotate in
azimuth on the stand.
There is an adjustable spirit level on the side of the compass.
A mirror is located on the inside of the lid with a vertical line inscribed for use as both a rear sight, as well
as to assist in reading the heading.
The front sight has a magnifying lens built into it, which can also be used to read the compass heading.
When the compass lid is closed, it moves a needle lift mechanism that protects the jewel bearing while the compass
is being transported.
The top of the lid contains a natural sine table and is labeled "Stanley London."
This compass measures 3 1/8 inches (7.9 cm) in diameter, stands 3 1/2 inches (8.9 cm) tall with the lid closed,
and weighs 1 pound, 10 ounces (740 grams).
In practice, the spirit level is calibrated by setting the compass on a relatively level surface and adjusting the
spirit level until the bubble reads the same distance from center when the compass is rotated 180-degrees on its stand.
With the spirit level calibrated, the three threaded feet are adjusted so that the spirit level is centered for any
azimuth.
When an object is sighted through the sights, the main compass rose determines its magnetic heading, and its heading
with respect to true north can be read from the outer azimuth ring.
The solid brass Stand Surveying Compass is offered at only $74.
