This instrument is known as a Richtkreis 31 (Rkr 31) and is termed an aiming circle. It was used with both artillery and fixed-mounted machine guns (MG-34/MG-42) to measure horizontal and vertical angles in preparation for indirect fire, e.g. over a hill or onto a reverse slope. The sight was fitted onto the standard German army wooden optic tripod rather than gun mounted to allow the user to predict and direct fire of multiple guns. The sight’s periscope is fitted to the aiming circle body by means of a dovetailed slide. Its function is merely to raise the line of sight, it has no magnifying power. The telescope has an adjustable focusing eyepiece, with a leveling bubble on top. To the left of the telescope is a spherical level by which the head can be leveled. The graduated angle-of-sight mechanism can be rotated and the traversing mechanism is graduated.
