I have several Herc Manuals and there are some on the avialogs site as well if I remember correctly..

Bristol Hercules documents

I have two Hercules manuals as far as I can remember. Here is the first, a post war manual from a pretty ordinary photocopy. The other is a fault finding manual from mid war from memory. I just have to find and scan it.
