Hi Nap,
Yes, Max Longhurst was a master of Historex. In the early catalogues almost all finished figures were by him.
I still think that Shep Paine's "On the Eve of Essling" is a masterpiece. But my all time favourite, the one that always inspires me, is a vignette of two carabiniers chasing down two Scots Greys, called "A Run for the Colour" by Andrei Koribanics. Find a picture of it somewhere, it will blow you away.
