No problem Kurfürst, just a matter of a few minutes and a good look at the RAF website vs. the combat reports on Mike Williams' site (is there not another source for these RAF combat reports anywhere else on the internet?). I'm not convinced myself that the supply was universal, but my personal impression is that at the very least 11 Group was converted almost universally before the battle "began".
Could I ask whether anyone is aware whether it's true (and I'm not sure where I heard this suggested) that the sector airfields and their satellites were supplied from the same depots? This would clear up a lot of the confusion, since we could then assume that many of the permanent fighter airfields were supplied as well.
Thanks VERY much for that link, fruitbat, I'll go through as many squadron ORBs from there as I can get to examine the 100 octane situation, when the squadron received CSUs, and indeed whether they were De Havilland or Rotol units, because if I remember correctly Kurfürst has posted in the past evidence that the De Havilland units were not as well-regarded by the RAF, and the widespread conversion to Rotol units afterwards seems to support this.
It's a pity the German record situation is not as complete or available.
