Northrop F-5 Public Domain Book Project

Hi all,

i’m looking for information about Northrop F-5/F-20 to be used in a public document that will be published in pdf and available to be downloaded in next december.

All information would be welcome but specially those related with the number and description of F-5 ancestors (N-102 Fang, a naval version for the F-5, a fighter called Tally Ho, and maybe four more design studies).

Photos and illustrations with proper authorization to be used in the book/document would be welcome too.

Thanks
