I found this book at Barnes & Nobles.  It's 'The Complete Book of World War II Aircraft'  If you are into modeling, you may want to check this out.  There are literally hundreds of 3-view drawings of WWII and earlier aircraft.  The only problem is the size.  It took 2 scans put together in Photoshop to get the scan for the Buffalo below.  This is only half the cover showing.  It's a great book however, and the drawings are incredible.  Price is $25.00, the ISBN number is 0-7607-2873-9. 



Here's a sample of the 3-view for the Buffalo...
