Battle of Britain - who shot what down?

[Icare9]

Is there already any definitive work that has examined each days action and established who shot what down?

It seems to me that this is one area that hasn't been exhaustively researched, not least because of the uncertainty when say a German pilot shot down a British aircraft but in turn was shot down himself, there wouldn't necessarily be any way of accrediting that in the melee of a dogfight..

However, this many years later we can establish what pilots took off from each side and who returned, so whilst it may not be possible to attribute a loss to a specific pilot, but perhaps to a likely unit.

Has this already been done, or is this an area that both the Allied and the Luftwaffe board experts can work on?
