Once it became clear that the locomotives would be used further afield than the West Country, a decision was made to name the remainder after RAF squadrons, airfields, commanders and aircraft that had participated in the Battle of Britain over Kent, Surrey and Sussex. 'Battle of Britain' nameplates incorporated the name of the locomotive with the class name below, in a design that resembled the wings of an aircraft. This was painted Air Force blue, though other colours were sometimes substituted for the same reasons as above. An enamelled crest of the aircraft, personality or squadron was placed below the nameplate, in the same position as the West Country class equivalent.
