Thanks guys, I appreciate your help but you are all pointing me towards the Pilots Notes which is not what I want, albeit the people at Flight-manuals appear to have the same Volume I which I can buy on ebay, so I’m no further on with my query.

Here’s the cover for the Volume I for the Wellington II. There will probably be something like 300 pages of text, photos and line drawings. This is what I’m seeking, for any variant of the Wellington after the Mk. I. [ATTACH=JSON]{“data-align”:”none”,”data-size”:”full”,”data-attachmentid”:3859331}[/ATTACH]
