Nice work Jim, really impressive weathering. I also saw that article by Marcus Nicolls it was great. I've seen much inspiring work by him over the years and it was his work that go me back into the hobby about 4 years ago.
Anyway having seen your's i may have to try a T55 sometime it's a cool looking build of an interesting AFV.
