The design of this badge derives from the centrepiece for the Home Service helmet plate of 1881 (ie after the numbered centrepieces had been replaced). The badge was modified in 1902, with a king's crown replacing the queen's, which helpfully dates this piece.

This is the OR's glengarry badge of the 5th Battalion. It was worn, with a Queen's crown, from 1887-1901, when the imperial crown (as chosen by Edward VII) replaced Queen Victoria's crown.
