THE BUFFS INFORMATION
The Buffs had a stable belt of Royal Blue, Buff and Royal Blue in equal width stripes, with a leather straps and buckles worn on the left-hand side. The same stable belt was used by the Queen's Own Buffs after amalgamation on 1 March 1961 until the formation of The Queen's Regiment on 31 December 1966. Your picture of the Queen's Own Buffs stable belt is correct except that the colours are inaccurate, appearing to be too greenish. As a former Regular officer in The Buffs, and later the Queen's Own Buffs (and The Queen's Regiment), I still have a Buffs/ Queen's Own Buffs stable belt in my possession.
