Hi Messy,
>Does anyone have or know the numbers of German planes shot down by Allied bomber crews and how the numbers break down by the various planes flown?
I believe the Strategic Bombing Survey has the kind of data you are looking for. However, the problem is the accuracy of the data as overclaiming was much heavier than with fighters - inevitably, I suspect, as the problems of damage assessment and "synchronization" between individual combat reports were extremely difficult for bomber units.
