100 octane fuel used during the BOB?
Ah yes, i did read about that at an other forum, very interesting read indeed.

I've seen this line on a website for Trimpel Oil refinery

By May 1940, reconnaissance Spitfires had begun flying combat missions using the 100 octane fuel. By 31 July 1940, there were 384 Spitfires serving in 19 squadrons using the 100 octane fuel.

There's no reference to where they got the 384 in 19 squadrons from.

Interesting link winny, thanks for sharing! Just as significant as the passage you quoted is this one in my opinion:

"Bulk supply contracts for higher octane fuel were placed by the Air Ministry and it was put into widespread use in the RAF in March 1940 when Spitfires' Rolls Royce Merlin engines were converted to use the 100 octane fuel."

This seems in agreement with other published sources, such as the one below from A. R. Ogston, although your earlier posting did show units converting in February 1940.

Interesting page on Heysham, thanks for sharing.

I would say its simple guesswork that it was used in all aircraft.

The funny thing you see is, with all the years and fantatic research, the fanatics of the cause could not produce but ONE paper stating even remotely saying such.

Its funny, compared to how allegedly 'uniform' its use was, that there's no single paper of it. Instead, the propagators just get wildly excited and hysterical, as usual, trying to make up with noise for something they cannot make up with substance.

It all reminds me of the old, now debunked claims by the same bunch of people at the ex-Spitfireperformance.com website. That time it was claimed 150 grade was a de facto standard fuel for Spitfire in 1944, and every Spitfire run just on that an nothing else. They even went as far as showing cropped original documents mentioning +25 lbs boosted Griffons, for example. "Only" the part of the paper that said that the engine failed almost immidiately was cut off... its funnily analouge to the current situation, because we have again cropped documents, oddly enough just forgetting about the period (May-September) in which Lord Beaverbrook noted that the conversion of the force halted.

Probably the simplest for would be get a full copy of AVIA 10/282 from Kew, as it would put all doubts to rest I believe.
