In the winter of 2012/13 DLR moved their production from Dunstable to Gateshead. They were unable to have the presses ready in time to print the new tariff stamps so the work was transferred to Walsall for the first printing. The £1.28 rate was unchanged and we understand that there were no Walsall printings. The new De La Rue printings of was circulating by the end of April.
