When this standard eventually began to wear out, in 1880, the Regiment sought a warrant from Horse Guards to replace it. This was refused on the grounds that it had been a personal gift of the Sovereign and was thus not official issue. It was last carried (on foot) in 1911 at the unveiling of the Victoria Memorial. It is not connected to the guidon now carried by the Blues and Royals, which comes from the Royal Dragoons. See Sumner and Hook (2001a), p. 54; World Flag Database: United Kingdom, Military Colours.
