Specimen copies in the form of die proofs of the uniform Colonial Design stamps were printed in late 1934 and circulated to the various Colonial Administrators for review. These original specimen copies showed the proposed design with the word "Specimen" in place of the name of the Colony. The duty (value) was left blank. Subsequently seven sheets of each stamp (with name and duty) were printed for U.P.U. distribution and perforated with the words "Specimen." Each printing company used a unique perforation style. Varieties such as the extra flagstaff and others have been described on these specimen stamps


Bradbury Wilkinson
The Bradbury Specimen perforator used was Type B9. This type was in use between 1928 and 1948 and has 67 holes. There are known specimen forgeries of British Honduras, Gambia, Jamaica, Newfoundland, Sierra Leone and Trinidad & Tobago.

De la Rue
The De la Rue perforator used was Type D19. This was the first perforator used by De la Rue and was used between 1928 and 1936. It appears that only one stamp at a time could be punched and thus the positioning of the perforations are somewhat irregular. There are 65 holes in the perforator. The perforator became quite worn and was discontinued after the jubilee issue (There are a number of Specimen stamps described with the "I" being only three, instead of four, perforations high). Forgeries have been described for Barbados, Ceylon and Fiji.









Of interest is that the Jamaica stamp booklet was produced by De la Rue. The specimen copies, Type D18, were overstamped with a rubber hand stamp in purple.



Waterlow and Sons
The Waterlow perforator, Type W8, was in use between 1928 and 1944. It has 70 holes. This was the first Waterlow perforator brought into use for U.P.U. specimens. Forgeries have been described for Grenada and the British Virgin Islands.
