"At our autumn meeting Col. Latham showed some of the abbreviated postmarks and asked for information about them. As several other members evinced an interest I have pleasure in giving the following details that an examination of my collection has brought to light :
Duplex 'A12' marks of the upright oval type were supplied for use at three of the St. Kitts villages and the island of Anguilla being distinguished by two letters above the date.
These stamps were sent out to the island from the G.P.O. London, on 10th May, 1900. The villages and abbreviations were :-
ANGUILLA = AN. DIEPPE BAY = DB.
OLD ROAD = OR. SANDY POINT = SP.
It would seem that there was a later issue of circular date stamps (non-duplex) with these abbreviated marks for I have the abbreviation 'SP' in a c.d.s. on S.G.76 of Leeward Islands.
Unfortunately, this is a single stamp and the year of the date does not show but it must have been 1922 or later. Any further information members can supply will be appreciated.
