WW1 MILITARY COMPASS, 1915

A prismatic Compass has a prism above the scale to enable accurate readings.
The cover hinges up and has a hairline across its glass front, this is lined up with a sighting slot on the other side.
Viewing through the sight and aligning the hairline with two distant known landmarks one at a time, enables the user to obtain their position on a map, by creating a triangle between the position of the two landmarks, and the compass readings taken and drawn on the map.

Donated by Francis Pitkin, this item was used by Mr Pitkin's father
