I found a training manual for the T-28 turboprop NA 62H-948 REV 12 DEC 1962. I don't know anything about planes as I do not leave the ground, however if some one needs this book I will gladly send it not selling but the manual is in really good repair and still marked as confidential so it could complete someones literature. the cover shows a t-28 drawing and the title reads U.S. ARMY WEAPONS TRAINER T-28 TURBOPROP. if this is something somebody could use it let me know and I will mail it.
