I read a while ago on a Warhammer 40k blog that people were trying to find the original Dark Angels Deathwing Chapter original story, only published inside of the rules of the Deathwing expansion of Space Hulk.
Well, I have something that might interest you. Specifically, that story scanned in PDF.
All the 19 pages (including a cover) containing that original story, in english. It's a full page scan (no OCR) and it looks a bit worn of on the borders, but it is perfectly readable.
UPDATE: Downloads section no longer exists.
