I believe we have 3 different manuals for the CD. The best one is designated US Navy Blackstone and is of excellent quality (best I have ever seen for the WWII era) very thorough and explicit and plenty of pictures and diagrams of everything in your engine... as a reprint will cost you $40. As far as electronic manuals go, we do have some of them scanned. File sizes tend to be excessive for normal electronic transmission though. I am not sure where other CD resources are located at present unless Smokstack or the Forbes museum site might have some.
