Rare Antique Sextant H. Hughes & Son London (1903-1939) - Original Box and Certificate, Coeval Serial Number 7567
Fascinating antique nautical sextant from the illustrious British manufacturer H. Hughes & Son Ltd, London, engraved directly on the main arc (graduated arc).
A piece of utmost historical and collecting interest: the instrument is supplied complete with its original solid wood case, inside which the original Certificate of Examination and Testing dated 1939 is perfectly preserved (issued in Copenhagen shortly before the outbreak of the Second World War). The serial number impressed on the sextant’s metal (7567) matches 100% with the one reported on the paper certificate, guaranteeing absolute contemporaneity and authenticity of the set.
Condition and details:
Mechanical body: Excellent and robust, brass-burnished with the splendid patina of time from sea use.
Optics and mirrors: The index mirror, the fixed horizon mirror, and the magnifying lens mounted on the movable arm for reading the scale are intact and in perfect order. All sun filters in a fan shape (both front circular and rear square) are present and functional.
Accessories: Includes the original wooden box with green cloth and an original sun cap made of surviving brass. The tubes for interchangeable telescopes are missing.
The Case: The central recessed lock was removed at some point (likely due to key loss or lock mechanism jamming during wartime use). The box closes securely with the two original side latch hooks that engage their respective pins. The external brass carrying handle is original, solid, and fully functional.
A true piece of maritime and scientific history from the 1930s, perfect for discerning collectors or as a prestigious decorative item.
