An absolute holy grail for collectors of militaria, history of science, and medical antiquities: an original, monumental World War I British War Office Major Field Operating Surgical Set. Manufactured by the legendary instrument makers Arnold & Sons, Giltspur St., London, this chest is an unprecedented, museum-quality "time capsule" from the Great War. Crucially, this set appears to have never been deployed or used. The majority of the instruments still retain their thick, original 110-year-old maker's protective packing grease coating the steel blades and mechanisms. The set features multi-tiered, perfectly fitted velvet trays housing an extensive array of specialised instrumentation, every piece clearly stamped with the Arnold & Sons name and most with the British military Broad Arrow ordnance mark.
 
The Comprehensive Instrument Array Includes:Two heavy craniotomy/trepanning skull drills with a interchangeable handle. A magnificent, heavy capital bone amputation saw. A complete suite of all-metal dissecting knives, catlins, and scalpels (complete except for 3 empty slots). Fine silver tracheostomy tubes, trocars, and specialised cannulas. A mechanical tourniquet, completely pristine and never uncoiled. A nested set of surgical tissue retractors, remarkably still bound together by the maker's original factory wire, unopened, original paper packets of surgical suturing needles. The Cabinet:Housed in its heavy, masterfully crafted brass-bound solid mahogany case, with key, but the key does not operate the lock. The inside lip features clean celluloid manufacturer plaques reading "Arnold & Sons" and  "Giltspur St., London". The flush-mounted exterior brass top cartouche is crisply engraved with the official military designation: "INSTRUMENTS OPERATION" including the official Military Broad Arrow property mark.

Collector's Presentation Note: While used or compiled surgical kits cross the market, finding an officially marked WWI British Field Operating set that has slept undisturbed in this pristine, factory-greased state for over a century is a vanishingly rare, investment-grade occurrence. An unrivaled centrepiece display for the world's finest medical or military archives.
 
Arnold & Sons were the cutlers to the Empire and the Frontlines they were founded in London in 1829 by James Arnold (initially trading under his own name before formally becoming Arnold & Sons in 1866 when his sons joined the enterprise), the firm rose from its home in West Smithfield and Giltspur Street to become arguably the most trusted name in British surgical manufacturing. Centred adjacent to St. Bartholomew's Hospital, they established a reputation for uncompromising mechanical and metallurgical excellence, earning multiple Royal Warrants. However, it was their role as a primary contractor to the British War Office and Admiralty that solidified their global footprint. Pioneers of aseptic military surgery during the late 19th and early 20th centuries, as the understanding of germ theory and infection advanced, military surgery underwent a radical transformation. Arnold & Sons were at the absolute forefront of this technological shift. They pioneered the transition away from traditional, luxury "gentleman's" surgical sets—which used porous, un-sterilisable handles made of ebony wood, tortoise shell, and ivory—toward all-metal, silver-plated, and nickel-plated instrumentation. Arnold & Sons redesigned their entire catalogue so that tools could be repeatedly boiled, autoclaved, or subjected to harsh field sterilisation chemicals without degrading the blades or joints. When the British War Office required rugged, drop-tested, and flawless instruments for the field, Arnold & Sons was the empire’s answer. At the outbreak of the Great War in 1914 Arnold & Sons factories focused heavily on producing specialised military kits: Casualty Clearing Station (CCS) Chests: Heavy, brass-bound mahogany and iron transport trunks containing multi-layered operating theatre layouts. Trauma and Triage Tooling: They manufactured capital amputation saws, heavy bone-cutting forceps, and skull-trepanning drills designed specifically to deal with the unprecedented shrapnel and blast injuries sustained on the Western Front. Veterinary Excellence: Beyond human medicine, Arnold & Sons was also the chief supplier of veterinary instruments to the Army Veterinary Corps, providing horse slings and specialised tools to care for the hundreds of thousands of horses serving on the frontlines. When an Arnold & Sons instrument was stamped with the government's Military Broad Arrow, it meant the piece had passed stringent War Office material inspections. Their tools became legendary among frontline surgeons for retaining a razor-sharp edge under the most brutal, muddy, and chaotic battlefield conditions. Today, an Arnold & Sons military chest is not viewed merely as a collection of vintage cutlery, but as the pinnacle of industrial-era medical engineering that helped lay the foundation for modern trauma surgery.
 
The case measures 45 x 17 x 8cm (17.7" x 7" x 3.15").
