"By the by, if anyone has handy scans of the America storyline, that'd be interesting to see."

There is actually a scan online from America, which Colin also drew, and it is the one you can see referenced in the flashback on the first scan you've posted above:

You can see that he was using a more painted style then, as was the fashion at the time - he now usually uses a more traditional pencilled and inked technique.

America is a classic Dredd story and well worth hunting out - I just checked Amazon.co.uk and the book is still in print and reasonably priced.
