A variety of brassards were worn by Naval Patrol or Police on duty. They were issued on a temporary basis to dutymen assigned to Naval Patrols or on a permanent issue to Patrolmen of the Boatswains Branch. Early patterns were identical to those worn by the Royal Navy and many were likely obtained from Royal Navy stores. Canadian manufactured brassards usually have snap fasteners with the letters UCC CANADA or UNITED CARR (United Carr Company Canada) stamped on the back of the snap.
