What you need is a copy of the book Anatomy of the Ship: The Aircraft Carrier Intrepid, by John Roberts. It contains a series of outstanding drawings of her in her WWII configuration - along with lots of photos and an informative text. If I remember right, this was the second volume in the Anatomy of the Ship series, from the Conway Maritime Press (UK) and the Naval Institute Press (US). Fortunately, though, it's been reprinted. Here's a link to an ad for it: http://search.barnesandnoble.com/booksearch/results.asp?WRD=John+Roberts+Aircraft+Carrier+Intrepid&z=y
Note that Barnes and Noble's used book dealer network has some two used copies available, one of them for a pretty good price. (Just click on the link on that page.) I've bought lots of used books that way, and I've always been completely satisfied. In this particular case, though, if you're a Barnes and Noble member you can get free shipping on a new copy; the shipping expense for a used one probably would more than offset the price difference.
Later edit: Here's a link to some more used copies, via Bookfinder.com: http://www.bookfinder.com/search/?ac=sl&st=sl&qi=y16sdymkVVrk.UV3Ni9qeHpH1fU_5788689723_1:5:213
Those prices include shipping, so there are some bargains to be had here. I haven't done business with this company myself, but my colleagues tell me it has a good reputation.
Good luck.
