We have seen from the case of the One Shilling of Issue 4 that more than one variety of perforation (and even of colour) may exist in the same printing, nor is it to be expected that in such cases samples of each variety would be preserved by the printers, since differences of perforation are more appreciated in philatelic than in printing circles. There is, however, a circumstance connected with the perforation of the vermilion Shilling which leads us to believe that the stamps of all these printings were perforated only as shown in the sample stamps of each consignment. We know that in 1881 the third printing of the vermilion Shilling was utilized for making a provisional stamp of Four Pence, and that all these provisionals are perforated B only. We therefore think it probable that all of the One Shilling value perforated B × A belong to the first printing, and all perforated B to the second and third, more especially as the stamp perforated B is much the commoner of the two varieties. We have extended this theory to the Six Pence as well, and in the Reference List we give in brackets after each variety the probable date of issue of the different perforations. One thing that is remarkable about the colours of both these stamps is that there are no appreciable shades of either, the colours being maintained unchanged in all the printings of each value, although in the books of Messrs. Perkins, Bacon & Co. the colour of the first two printings of the One Shilling is called “scarlet,” and that of the third “bright red.” In the unused state the Six Pence is very much rarer perforated A than with the compound, but the converse is the case with the One Shilling, in which B × A is by far the rarer perforation. The paper of the stamps of this issue varies a great deal in thickness, but this is more pronounced in the Six Pence than in the One Shilling, as the former value is met with on what can only be described as thin card.
