As Albert Ratman so correctly said, the only definitive publication for working on a Vulcan B2 is the AP101B-1902-1A
This 'Manual' was compiled by former RAF J/T - Mr Andrew Edmondson, who some of you may know as the "Engineering Director" of TVOC, who managed to slot it in between carrying out his "vital" fundraising and directing roles during a difficult time for XH558....
The same "Engineering Director" who on one of his rare trips to the aircraft had a stand up argument with myself about how I had fitted the Hyd Reservoir to the wrong side of the bomb bay.... This is despite the fact that to do so would not only have been impossible, but also contrary to the hundreds of other Vulcans built. I could continue
.....
Take the book for what it is, a nice history on the aircraft, but not an entirely accurate one...
