S!
Just to say about update intervals on technical literature. We do get some that are dated some time ago and have gone thru the whole process or whatever before being published. But also get urgent ones that are released very quickly and have to be done or added to the literature so safety is not compromised. So I would guess that especially during wartime if something critical came up then info would be passed to the troops fast in a way or another to prevent losses because of lack in information. I do not think RAF or any other air force waited a year before publishing stuff, even during war
An example would be also the Curtiss representative that went to study the Helldiver planes having strange losses due control failures. Reason was a pulley/linkage in the wing and in the end he ended up machining these things of better materials on a CV! All this during war time and in the field. So info came out fairly fast don't you think. So would it feasible to think that the pilot/technical literature was updated fairly quickly and urgent information was passed to troops in form of a bulletin or other means before the amendment could be added to the official literature? Just a thought.
