Vintage Brass Pocket Transit Compass, Kelvin & Hughes London 1917 Reproduction

Modeled after early-20th-century military surveying and geological transits, the compass features a heavy, octagonal solid brass case finished with a rich, chemically darkened antiqued patina.

The lid opens on an integrated hinge to reveal a polished interior sighting mirror, balanced by a flip-up vertical sighting vane on the front rim—a mechanism historically utilized by field engineers to map precise topographic grades and bearings. The top features an inlaid brass medallion prominently stamped with the commemorative fantasy hallmark "Kelvin & Hughes London 1917" beneath a British crown emblem, a classic characteristic of late-20th-century nautical export brassware.
