*British, c.1937, Royal Navy Cordite Carrier (Clarkson Case) No.58 Mk III, Barrow, Hepburn & Gale Ltd.*
A genuine Royal Navy cordite carrier, also known as a Clarkson Case, pattern No.58 Mk III, manufactured by Barrow, Hepburn & Gale Ltd., Bermondsey, London. Constructed with a cork body, canvas-lined interior, and leather outer covering, fitted with leather strap handles secured by copper rivets to reduce spark risk.
The base is impressed: “No 58 / III / B.H. & G. Ltd”, together with a partially struck serial number beginning “7”. To the side, the case retains a clear printed King’s Crown Arms, accompanied by the large stencilled “N” and War Department broad-arrow property mark. Of particular note are two boxed issue/inspection stamps marked “PM”, rarely seen in such clarity. Measures approx. 40.2 cm tall x 22.2 cm diameter.
Historical Note:
Cordite, a smokeless propellant developed in Britain in 1889, replaced gunpowder in naval artillery. To safely move these volatile bagged charges from a warship’s magazines to its guns, the Admiralty adopted the Clarkson’s Case – a flashproof, reusable carrier that protected the charges from sparks, static, and damage. Once filled, cases were hoisted mechanically to the gun decks and opened only at the point of loading, before being returned to the magazine for reuse.
The “No.58” designation refers to the pattern/size, while “Mk III” denotes the third refinement of the design. The large “N” with the broad arrow confirms Royal Navy ownership. The boxed “PM” marks are thought to denote proofing/inspection stamps applied after Admiralty testing, ensuring flash-tight integrity. Surviving pre- and early-WW2 examples with visible crests and inspector’s marks are highly sought after, particularly those from Barrow, Hepburn & Gale Ltd., one of the premier makers of naval leather goods in the early 20th century.
*Condition*
In good, honest condition for age and naval service use. The leather has developed a rich, dark patina with scattered scuffs, wear, and surface marks. Original stitching and copper rivets intact; strap handles sound with expected wear. Interior canvas lining remains firm and undisturbed. Unlike many examples, the Royal Arms remain clearly visible, with the boxed “PM” stamps crisp, and the base stamping very clear. Lid now absent, as is common with surviving examples. A fine, authentic, and highly displayable example of a Royal Navy cordite container. Please see photographs as part of the condition report.
