Search for TF-X programme (–> later F-111) info

Does anyone have some info regarding the early concepts and the other competitors that later lost out to the General Dynamics F-111 ???

All I found is this except from “Aerospace Project Review” Vol. 1, No. 2 (page 27) from Scott Lowther regarding a NASA wind tunnel model for the TFX !

Thanks for help Deino 🙂
