If you review my website
http://www.fuselagecodes.com and select the sub-section "Advanced Flying Training 2-E" you will find a selection of 10 AT-9 photos. These photos represent AT-9's with various fuselage letter codes ( V,Y,G, H, K...).
I am still looking for AT-9 photos for the following AAF's: La Junta (J), Roswell (W), Blackland (N), Brooks (O), Pampa (U), Maxwell (M),Moody (MO) and Turner (T). Keep me in mind should you run across any of these as I would like to include them in my website. Of course, contributors are always given photo /collection credit.
BTW, I had read where the AT-9 was not released for post-war surplus sales as they were deemed to dangerous to be put in the hands of civilians. True?
