Lionel postwar Girls Train set, complete

Lionel original postwar GirlÕs Train set with 2037 loco, 1130T-500 tender that is missing one step, 6436-57 hopper car, 6464-510 NYC boxcar, 6464-515 MKT boxcar, 6462-500 gondola with white canisters, 6427-500 caboose and the original white 1043 transformer. This set is really hard to grade because it is all original with strong lettering, the paint is not all chipped up but the issue is that it is very dirty from sitting probably in a basement. If you know how to clean the set it will clean well but we are selling it as you see it in the photo, dirty.
