Admiral The Earl St Vincent put us forward for reccomendation to be granted the title Royal in 1802 the year it was given to us. We were always taught as recruits,that in 1802 The Corps was made Blue , we then changed to Blue Facings, the colour of Royal Regts in the Infantry. I can't speak for the Cavalry, as I don't know. I am a Kentishman, and we had 2 County Regts. The 3rd foot, The Buffs, had Buff Facings, but changed to Blue Facings collar and Cuffs when granted Royal title. They became , The Royal East Kent Regt,( The Buffs). The 50 th Foot , The West Kent Regt , had Black Facings, again changed to Blue when they became, the Royal West Kent Regt, 50 th Foot. My maternal grandfather was a Sgt in the RWKs. A lot of Londoners served in this Regt, as years ago before Boundary changes Kent went right up to the River Thames, as did Surrey. Another mark of a Royal Regt is the wearing of a Crown with Lion above it wearing a small crown, the RMs have this in their Cap Badge, but there could be some that although being Royal did not always wear it.
