This 19th-century antique marine stick barometer features a solid brass cylindrical body and is equipped with its original brass gimbal wall mount, which historically allowed the instrument to remain perfectly vertical and stable against the rolling motion of a ship at sea. Measuring 87cm in length, the silvered or ivorine dial measures barometric pressure from 27 to 31 inches, displaying traditional meteorological indications from "Stormy" to "Very Dry," and bears a maker's mark indicating it was manufactured in London. Structurally complete with its integrated thermometer, manual vernier control knobs, and a protective weighted lower cistern casing, the piece shows an authentic, aged dark patina with minor surface oxidation, light scuffs, and expected wear consistent with its age and maritime heritage.
