27 March 2013 88p stamp - 20g airmail rate to Europe.
Printed by Cartor in litho.
For the new postage rates in 2013 the rate increased from 87p to 88p.
Cartor's first printing of this and the other country stamps was on 14/01/13.
A second, unannounced, printing on 31/05/13 was from new plates with a different arrangement of the countries on the plate. This should have been plate 2 but the numbers shown are C1 for all colours.
The Scotland stamp is probably the least distinguishable but the new one is lighter. The image shows the 1st printing on the left, and 2nd printing on the right.
