As a postscript, I had a second CF7 to weather. There didn't seem to be many photographs of this livery, and those that I did find showed it in pretty clean condition. As Chris wanted it to be really filthy, I had to resort to photographs of the FEC and also looked at photographs of locos with a similar paint scheme to see what they looked like when grubby. The attached images show the final result. I am afraid the images aren't too clever as it is as murky as Hell here today, so I had to use flash which isn't ideal.
