Quite right C_G, the Clean Air Act and the a change from using solid fuels to gas in 1970s means the air at lower levels in especially urban Britain is much cleaner than it was in the 1940s. Much of this black air would coat everything. Back in the , 70s, and 80s many old and historic buildings were cleaned. I still remember York Minster and the railway station there with their coating of industrial grime. Both were cleaned up in the 70s and 80s and have gone from brown and black to their natural stone colour. The Old Dart must of looked very grubby back when.
