During World War One and Two, service personnel were issued pressed fibre identity disks, one green octagonal shaped disc, and a red round disc (some army units issued a second red round disc to be attached to the service respirator). The identity disks were hand stamped with the surname, initials, service number and religion of the holder and if in the Royal Air Force, the initials RAF. The disks were worn around the neck on a 38" length of cotton cord, this was often replaced by the wearer with a leather bootlace. One tag was suspended below the main tag.
