Bomber Command during BofB
 

Hi,
as additional material to research about few bomber squadrons during BofB, I'm looking for the copies of following documents:

AVIA 7/3767 - Bomber Command monthly tables of effort, losses.
AIR 14/927 - Bomber Command monthly summaries
AIR 14/933 - Bomber Command: summaries sorties, casualties

(copies or specific information related to few operational nights).

Especially interesting for me period is September-October 1940.
I will be thankful if anybody could help.

of course I have a "BC war diaries", I'm looking for the more sources of information.
