Back at the beginning of this year, as part of a separate project to digitize a collection at our museum, I scanned a copy of an operating report for Fisher Body's aircraft program. It has a bunch of rare photographs, statistics, and details about production of gyroscopes, compasses, B-17 exhaust systems, B-25 components, B-29s, B-19 and XB-39 engine testing, and development of the ill-fated P-75 project. I thought everyone here might like to take a look, so here's a link:
Fisher Body Division Operating ReportEDIT: Before anyone asks, the report belongs to one of the museum's volunteers. It was part of a collection of "B-25 documents" he purchased sight unseen. So, sorry, I don't have any more information about its provenance. Also, yes, it is missing pages, and no, I don't know where they are. I scanned every page that was available to me.
