King’s Own Scottish Borderers (KOSB) collar badge (1887–2006 pattern), an original example of British Army uniform insignia associated with the King’s Own Scottish Borderers.
The badge features the regiment’s distinctive device in relief, incorporating the regimental title and a three-turret castle, similar to the cap badge used throughout its long service history. Designed as part of a pair, collar badges of this type were worn on both sides of the tunic collar and formed a key element of British infantry service dress identification.
The 1887–2006 pattern spans a remarkably long period of use, covering the reigns of Queen Victoria, Edward VII, George V, George VI, and Elizabeth II. It remained in service until the regiment’s amalgamation into the Royal Regiment of Scotland in 2006.
Collar badges of this type were issued to all ranks and were an important visual identifier of regimental identity, complementing the cap badge and shoulder titles. The King’s Own Scottish Borderers traced their origins to 1689 and built a distinguished service record across many campaigns, including both the First World War and World War II.
Manufactured in brass with original attachment fittings to the reverse, this example represents a classic and long-serving piece of Scottish regimental insignia.
