I have an A4000 user's guide, the AGA Graphics Supplement insert and an Amiga Hard Drive user's guide.
I no longer have an A4000 so we can work something out.
I will take some pictures and post them on a hosting system for you (if you are still looking for these that is).
I can't recall what was in a complete set for the A4000, as I may have more books stashed away some where (these are the one's that I found on my book shelf)
