1923 Formula Registered Envelope to England with a 1d, 2½d and ½d, correctly paying the 4d rate, cancelled FALKLAND ISLANDS OC 4 23. A Falkland Islands (Stanley) registration label is on the front of the cover along with a Maidstone 23 NO 23 arrival cancel. On the back is a Registered Liverpool 22 NO 23 arrival cancel. This letter would have been on board the ‘S.S. Oriana’ that left Port Stanley on the 4th October and returned to Liverpool via the Panama Canal. Fine.
