Group companies kept their funnels and individual flags, with the group flag flown alongside or above them. G.H. Watt recalls the individual flag always below the group flag on the mainmast. Clan-named ships used their individual name tartans in place of the red background on company stemjacks until the practice ended in 1966–67 because of cost. World depicts a royal-blue group flag with the saltire extending 60%; Rosanoski disputes its black diamond outline from film evidence and judges proportions nearer 2:3 than 1:2. The National Maritime Museum B558 specimen is dated 1955–67 and measures 1270 × 1778 mm.
