The postage rate increase in the spring required new country definitives, as well as Machins.
The Scotland 88p was printed on 14/01/13 with cylinders C1 phosphor, silver, yellow, magenta, cyan and black.
Unusually the black had a different font, with a narrower 'C' and with the figure 1 pointing down, rather than ending horizontally as on the other colours. Close examination of the phosphor cylinder number shows that to be the same as the black, but the phosphor 'C' is of a third type, being similar to the colours but with the two ends truncated and pointing only slightly down and up, ie ending almost horizontal. This is impossible to show in an ordinary scan.
With the fonts available on this blog, the black C and 1 are similar to Arial, the phosphor C is closer to Verdana. What you see, of course, may depend on your browser settings.
Thanks to AM we can show the cylinder block from the 31/05/13 printing.
But this begs the question, do cylinder numbers really mean anything now, to Royal Mail or the printers? Why were the cylinders not changed to C2?
