Of course it is not the same document, as said it's from the 1st edition. If you read the preface of the 2nd edition you will notice that it has been "revised and rearranged in convenient order and grouping". That's why they are not comparable.



This is the whole page where the 100 octane limitation was taken from.

And it's perfectly in line with the 100 octane limitations of various Merlin engine manual from January 1939 to November 1940:

March 1940: http://www.spitfireperformance.com/ap1590b.jpg
November 1940: http://forum.1cpublishing.eu/attachm...5&d=1337196053

These are several other quotes from the 1st edition of Pilot's Notes General.

I'm sorry, I do not intend to provide a whole digital copy, it's a very rare item. Not sure if The National Archives has one and I've never seen it somewhere else. You can PM me if you have something pleasurable to offer as an exchange.
