cover 1900 (24 Sept.) XU5 to Hong Kong, bearing G.B. 1d. cancelled at F.P.O. 51 and showing, above the address, oval d.s. "CANADIAN CONTINGENT/SOUTH AFRICA", a good to fine example in violet, transit (Colombo) and arrival d.s. on flap. Overall discoloration but rare, and a very unusual destination. Photo.
