This is a vintage liquid-filled marine compass housed in its original protective wooden box. The compass features a gimbaled mounting system, allowing it to remain level despite the motion of a vessel. The black compass dial is marked with directional degrees and cardinal points, clearly visible under the glass casing. A brass instruction plate is mounted on both the exterior front and the interior lid of the box, reading: "IF AIR BUBBLE APPEARS / TURN COMPASS OVER SLOWLY / TO DISMISS." This indicates a liquid-damped design typical of early to mid-20th-century maritime navigation equipment. The wooden box features a rich, warm patina with a simple metal latch mechanism on the front. The piece is in good vintage condition, showing signs of age-appropriate wear, including minor scuffs and scratches on the wooden box and some oxidation on the metal components. This classic nautical instrument makes an excellent display piece for collectors of maritime history or scientific instruments.
