Just to make sure you know, just above the 6 numbered links for the build pictures is another link for the parts to build the standing version of Pilgrim 7000. I'm surprised no one suggested a model of the ABC Warrior from Judge Dredd.
I would actually prefer a model of Hammerstein that it was based on from the comic 2000ad but I remember the film version of an ABC Warrior was quite a hot topic at one point.
