Neither the 1:500k nor the 1:250k for the area have the new Manch LLR details on them. The new boundaries etc only came into effect on 8th March and the charts were published on 5-5-11 (1:500k Sheet Edition 34) and June 2011 (for the two 1:250ks covering the area).
The next edition of the 1:500k is published on 3rd May. You won't get new editions of the 1:250k till May 2013. Details
