I was wondering if anyone here could help me in tracking down additional information for a high-res image. In the Assassins Codex, there is a small drawing of a Callidus assassin similar to this piece of fan art:

People have told me that the original drawing (the one in the codex, not the fan art) was done by Dave Gallagher who also did one of a Vindcare assassin. Apparently both appeared as large, high-res images in a WH40k art book. Therionweb.de used to have both large images (each scanned with a "T" in the lower corner) but now Therionweb is no more. Does anyone have any contact information for Dave Gallagher or know which book specifically had the original images, or any additional information?
