2x Cavalry/Yeomanry NCO's Arm Badge (c. WWII)
 
A badge of the Prince of Wales's plumes, coronet and motto with two fixing lugs to reverse.
 
The Prince of Wales's feathers are the heraldic badge of the Prince of Wales, the heir to the British throne. The badge consists of three white ostrich feathers encircled by a gold coronet. A ribbon below the coronet bears the German motto Ich dien (German: [ɪç ˈdiːn], "I serve"). As well as being used in royal heraldry, the feathers are sometimes used to symbolise Wales itself, particularly in Welsh rugby union and Welsh regiments of the British Army.
