SR Southern - White/black specific lining set for M7 Class loco in Maunsell Era. It has to be said that locomotives which carry a lining design which butts to the edges of the various panels is not the easiest scenario for which to cater. This is due to a number of factors - the M7 is an excellent example - and British Railways designs are much easier to acommodate. Some touching-in of the black areas by hand will be required.
