If the later version of the Operating Instructions does not include it, you can bet the earlier did not.

That looks like somebodies photo-shop work.

Here is the page from "Operational Notes for Pilots on Merlin II and III, 2nd Edition January 1939".
As I'm holding it in my hands right now I can assure you that it is not photo-shopped.

Actually I was wrong, the use of higher boost than +6 1/4 was according to this manual not only allowed for take-off but also for emergency.

Can I ask again for a link to the notes you are looking at or the parts where they refer to the propeller in use or the section on protection for the pilot.

The notes you quote do not seem to tie up to what is know about the updated version of the Spitfire in use during the BOB.

I am happy to be wrong but would like to look into it in more detail
