The stringed bugle was the symbol for Light Infantry and Rifle Regiments. The Kumaon Rifles was raised during World War One so this silver badge on a coiled green cord backing was worn on the khaki service dress forage cap. The number 50 was allotted to the regiment as it was vacant following the re-numbering of 1903. Another version of the badge post-1923 was the stringed bugle with KR above.
