Thanks! Yes, I think 1984-7 was a golden time for Citadel. The centre and right-hand orcs are by Trish Morrison, I think, while the one in the mail shirt is a Perry (with a version of Fangor Gripe's head with two eyes).
Here's the fifth chaos horde. Together with the sneaker, they make up a third of a standard HOTT army. The hero takes them to halfway. Then the ravage bear from a few pages back adds another 4 points as a behemoth, and the two salamander warbands can stand in to add 4 points more. I have two Bones driders that I serendipitously based on 60 X 40 bases two years ago which can be quickly finished, and that's a full 24 points. Of course, many more hordes are in production, and I have plans for flyers, more behemoths, a magician and a dragon ...
