3rd County of London Yeomanry (Sharpshooters)
4th County of London Yeomanry (Sharpshooters)
In 1938, as the threat of war increased, the Territorial Army was called upon to double its strength. Unlike most other regiments which split in half, the 3rd CLY remained virtually unchanged and the 4th County of London Yeomanry, as the new regiment became known, was built up from a small cadre of junior officers and senior NCOs.
There is no connection between this 4CLY and the original 4th County of London Yeomanry formed after the Boer War and later known as the King's Colonials and King Edward's Horse, which was disbanded at the end of the World War I.
