1908 PPC from Scotland to "Miss Darling/Christmas Island/co Messrs Bousteads & Co/Singapore" with KEVII 1d tied by very fine 'PORTPATRICK/WIGTOWNSHIRE' cds & Singapore transit of DE18/1908 on the address side. [Because this card was sent via a forwarding agent, it most likely went between Singapore & Christmas Island in a sealed bag]
1956 commercial cover from GB to "Royal Naval Weather Station/Christmas Island/Indian Ocean" with very fine Malayan-pattern 'CHRISTMAS ISLAND/18OCT56' arrival b/s, redirected to "BFMO/Singapore" & then to the Admiralty in London with 'POST/OFFICE - MARITIME/MAIL' machine b/s. Very scarce inwards mail.
