My website of
http://www.fuselagecodes.com has a wide variety of period BT and AT aircraft photos that should assist anyone modeling these A/C types. Included are photos from all the seven BFTS as well as target tugs and other miscellaneous types utilized. I continue to make photo updates on a weekly basis. My goal is to have a photo depicting the markings from every BT & AT AAF during WWII. At this writing I have a photo from nearly every AAF that flew the BT-13 / 15 Valiant.
