I found a link for the Bentley manual and thought it might be handy to share. I did do a search and couldn't find this posted elsewhere, but if it is please let me know and i will delete the post. Similary, if it is felt it should be posted under a different section please feel free to move it. https://drive.google.com/uc?id=1_HHN3DRos2j5Ja7zIQwcbGQgVqbzNEZu&export=download I have virus checked it and as far as I am aware it is fine but if you do download it I would advise carrying out your own check.
