A remarkably preserved piece of World War II maritime history: an authentic, original U.S. Navy Bureau of Ships 4-Inch Boat Compass (Mark I) inside its original copper slant-front binnacle housing. Manufactured in 1940, this heavy-duty navigational instrument was standard equipment on smaller U.S. Navy vessels and lifeboats during the onset of the war.
The binnacle casing is constructed entirely of robust, weathered copper and brass, featuring a heavy mounting bracket on the back and a brass carrying handle at the top. The interior of the main compartment retains its classic white paint to maximize light reflection for night navigation. Attached to the side is an independent burner box that opens to house its original liquid fuel/oil reservoir lamp with an intact wick assembly. The top of the lantern chamber features a vented chimney cap.
The fluid-filled gimbaled compass features a clear white dial marked in 10-degree increments and cardinal directions, fully floating and functioning as intended. The outer black bezel ring is crisp and clearly stamped: "U.S. NAVY BU. SHIPS", "4" BOAT COMPASS", "MARK I Ⓝ 2179-1940", along with the maker's mark "LIETZ 19198" along the upper rim. This is an exceptional, completely intact artifact for maritime collectors, WWII historians, or high-end nautical decor.
Maker Biography: The A. Lietz Company
Founded in San Francisco, California, in 1882 by German immigrant Adolph Lietz, The A. Lietz Company grew to become one of the premier American manufacturers of nautical, surveying, and engineering instruments. Renowned for their incredible precision, Lietz transit levels, sextants, and compasses were heavily relied upon during the reconstruction of San Francisco after the 1906 earthquake.
As the United States prepared for involvement in World War II, the U.S. Navy Bureau of Ships contracted specialized American precision manufacturers like A. Lietz Co. and The Lionel Corporation to rapidly produce rugged, standardized military-grade equipment. This Mark I boat compass is a direct product of that wartime mobilization, reflecting the high-caliber craftsmanship that helped define the company before it transitioned primarily into equipment distribution in the mid-20th century.
Historic Information & Interesting Facts
The "Bu. Ships" Legacy: The Bureau of Ships (BuShips) was established by Congress in June 1940 to supervise the design, construction, and maintenance of the massive fleet needed for WWII. This compass represents one of the earliest pieces commissioned under this new bureaucratic authority.
Dual-Lighting Design: These binnacles were ingeniously versatile. The side box holds a traditional kerosene/oil burner to keep the compass visible under emergency conditions or on lifeboats without electrical infrastructure. However, it also features a threaded cap on the lantern assembly that could be fitted with a detachable electric bulb socket when DC shipboard power was available.
The "N" Mark: The stylized letter Ⓝ stamped on the bezel denotes that the compass is an authentic Naval-specification design, built specifically to resist the extreme vibrations, moisture, and corrosion of oceanic combat zones.
