Material: Brass
Size: 10mm w × 12mm h
Description: The compact, cast brass device takes the form of a bold uppercase letter R sculpted with standard block typography. A distinctively grainy, non-reflective texture covers the entire face to minimize battlefield sun glare on formal service clothing. Two stout, bendable metal slider blades sprout directly from the rear plate to slide easily through tailored jacket buttonholes. A sturdy, circular loop loops outward along the right margin to accommodate a structural tensioning cotter pin. The simple profile retains a highly utilitarian, military-grade appearance engineered exclusively for severe administrative field wear.
Reverse: Flat back with 2 soldered lugs and pin
Circa: 1920-1960s
Notes:
This individual letter designation belongs to a unique category of British and Commonwealth dress regulations identifying British Army Officers (ROs) who occupied key administrative staff roles at headquarters after their formal service. The dual-prong backing layout allows it to mount flatly on specialized gorget patches, uniform collars, or epaulet tabs without shifting during movement.
