The "sword" is the central charge of the "crossed sword and Pipe Chanter" to commemorate long service with the Scottish Constabulary. The "Pipe Chanter" signifies the splendid record of the armiger's wife's family as Pipers to the Cluny Chiefs, the most notable being "Calum Piobair". The "book of learning" refers to Eoin's great grandfather who was first Headmaster of Daniel Stewart's School, Strathtay. The "wing" commemorates the armiger's service in the RAF during WW II.
