In his secondary role, as postmaster to the B.A.N.Z Antarctic Research Expeditions, Stuart Campbell was given two cancellers at the start of the second expedition in November 1930, it appears that he used one canceller on mail for the rest of Discovery's crew and kept the other exclusively for his own use.
