A rare piece of British military history, these vintage 5-inch wing dividers were manufactured in 1953 by the historic toolmakers John Berry & Son of Sheffield, England. Established around 1820, John Berry & Son became renowned for producing exceptionally robust trade tools from high-grade Sheffield steel. During the mid-20th century, they were a key contractor for the Ministry of Supply, manufacturing precision instruments engineered to withstand rigorous field use.
This specific instrument is stamped with the official British War Department Broad Arrow ($\uparrow$) ordnance mark, alongside the manufacturer name, the 1953 date, size mark "5", and military stores pattern code "H/484". Wing dividers of this era were essential kit for military engineers, cartographers, and workshop technicians, utilized for precise geometric measuring, scribing lines on sheet metal or leather, and mapping distances.
A superb example of mid-century industrial engineering, this collectible tool features tapered legs, sharp scribing points, a smooth hinge pivot, and a beautiful authentic patina.
