content: This is a standard Brunton Pocket Transit that, despite the "LIETZ 8026-51" inscription, was probably made by Ainsworth, and likely dates from the third quarter of the 20th century. The U. S. National Imagery and Mapping Agency transferred it to the Smithsonian in 2000.
label: Description
content: This compass has a folding sight at north. The lid, hinged at south and provided with a sight line and small hole, serves as the second sight. Since the lid is mirrored, the user can read the needle while sighting a distant object. The needle ring is graduated to degrees. The western half of the face is graduated in degrees, in quadrants from west, and provided with a clinometer for use when the instrument is horizontal, and a straight level for use when the instrument is vertical. Because the sides of the case are flat, the instrument can be set up vertically when used for vertical angles. There are also a metal tripod and a leather carrying case.
