Pilot's Notes were issued but then revised constantly, so an issue date of July 1940 does not mean that all the info therein dates to July 1940, but in any event, even if it does, publishing the 87 octane limits are still prudent, since an aircraft may land at a training field, or even a civil airport and be forced to fuel up with 87 octane. Additionally, OTU aircraft may have run on 87 Octane and hence the info would still be needed, and overseas 100 octane was still scarce, and the writers could not know where an aircraft might be operating.
The fact remains that there are no published reports stating that Hurricane/Spitfires used anything but 100 octane during the BofB.
My friend has a car with a HO engine, and it requires 100 octane fuel, but the owners manual contains info regarding lower octane fuel use and prudent operating cautions.
