Hello mongoose44
In Martin Middlebrook's The Berlin Raids. RAF Bomber Command Winter 1943-44 there is appr. 18 maps on routes used by BC during raids during Your timeframe. There are different editions on the book, mine is the Viking's 1988. Middlebrook has also wrote books on Hamburg raids in late July 43, on Peenemünde raid in Aug. 43 and on Nuremburg raid in March 44.
In Ken Merrick's By Day & By Night. The Bomber War in Europe 1939-45 (1989)there is appr. 6 maps on routes used by BC during raids during Your timeframe.
There seems to be only one route map of the raids made inom Your timescale in Alfred Price's Battle over the Reich. But I have an old edition (1973).
