Order of Battle for RAF Bomber Squadrons

Hello everybody!
Do you have any information about Order of Battle for RAF Bomber Squadrons?
I`ve been working on a history of one of polish bomber squadrons for a while and I would like to gather more information about their organisational structure.
They were initially equipped in Fairey Battle and then in Vickers Wellington and finally in Avro Lancaster aircrafts…
I would like to find any available info about the required quantity of crews and aircrafts (operational and reserve)…
Is there any way to get more details about it?
Regards to all,
Grzegorz
