I shall be going to Erith next weekend to do part of the Green Chain walk from Erith to Falcoln Wood via Lessness Abbey Wood and Bostall wood. I shall have a look out an old factory building with chaps still trying to clean solidified gloop from the walls.
Meanwhile, your post has made page one of a google search for 'Marmite Factory Crayford'.
