These belonged to a friend of mine's father who served there and stamped his name on them all. Very Good to Excellent condition, little or no wear and not much aging. All are command manuals and I think the CO one is of great interest just at face value, but I would not discount those on drill or post duty either as plainly that is what much of Army life was about. Individually $10 each or upwards but they are more historic as a comprehensive group.

Texas airfields especially San Antonio trained a major share of the aviators and airborne fighters who carried much of the war across both oceans. This set of manuals is a big part of that history. The course outline is not many pages, the Post Duties is 150 or so pages and the others in between, maybe 350 pages roughly among the lot of them.
