Steve not quite what you wanted but is this plan of use ? (actually a later raid).
You may have seen Andy's magazine article on the 1942 one.
Added....the map is from the National Archives, AIR48/83 "US Strategic bombing survey reports" no.2. Unfortunately this is not digitilized yet. Part 1 may have another plan.
There are also 2 PR photos of the plant identifying shops and sheds etc. in IMPACT magazine Sept. 1943. If you want to see them you can PM me your e-mail.
(This is after the Eighth AF Mission 49 of April 4 1943.)
