Pocket Sextant - 2
A First World War pocket sextant from 1915. These were used in the trenches, but not to "shoot the sun" and determine position, but rather (turned through 90 degrees from the normal orientation) to measure horizontal angular distance from a known fixed point and hence allow field guns to be aimed more accurately. From its general condition and the slight bend in the arm supporting the magnifying loupe, I suspect it saw service in WW1. The visible extent of the image is 3".
