P-38,B-25,B-17 Cutaways

Found this site while trying to find out what those two bumps behind the B-25 upper turret were for. There are three PDF files for the above mentioned aircraft and they are downloadable. Each one is between 27-31 pages long. The P-38 file say it is #8 but as yet I haven't located the other five. I won't post the PDFs here not being sure of copyright stuff. Here is the web site.
