Just like this one, it will specifically state if they are using the fuel.

Throw out the ones that just note conversion like this one:

Note what the 611 Sqn ORB says:

21/3: Fuel: The new aircraft are one by one being converted...for the use of 100 Octane fuel, instead of D.T.D 230.

By arbitrarily "throwing" the 611 Sqn ORB out because it says "conversion" instead of "using the fuel" the fact that it notes that 100 octane fuel was being used instead of 87 octane is completely missed, plus it says 9 aircraft converted. So dump that "rule".

Here are two other ORBs from February 1940, from before before the issue of AP1590B/J.2-W, March 20 1940. That's four squadrons, plus four airbases North Weald, Digby, Hornchurch (11 Group) and Drem 13 Group confirmed to be converted or in the process of being converted to use the fuel in Feb-March 1940 alone. All indicate that 100 Octane fuel was the only type of fuel being used by converted aircraft.

Before you say "only four squadrons" these are ORBs of the time which have been found so far, that does not mean that these were the only squadrons in the RAF to convert.

Those from February also show that the conversion of Merlins was well underway before A.P1590B/J.2-W was issued, confirming what the document says.
