This is a 'Trough' or 'Plane Table' compass, a type of instrument first used in the early 19th century, and which saw extensive use during WW1. According to compassmuseum, 'A trough compass consists of a long, narrow rectangular box, covered with glass. Inside the box, at its centre, there is a magnetic needle resting on the pivot. At the extremities of the trough compass, there are (sometimes but not always) graduated scales with zero at the centre and degree markings on either side of the zero line. The trough compass is used for marking the magnetic north line on the drawing sheet of the plane table. In this case, the magnetic needle points to 0° - 0° of the graduated scale and a line drawn parallel to the edge of the trough compass is along the magnetic meridian. A trough compass is also used to orient the plane table with respect to the magnetic meridian'. During WW1 this type of compass was used for artillery work. A later example of the Dixon's Military compass can be seen at compassmuseum.com.
