Can't tell which one it is, but 44-8543 is in some of those pictures, and my wife and I have spent a goodly number of hours working on her when she was still in Fort Worth with the Hospers family. These are some of the best pictures I've seen of the three Dothan Forts. We also had lots of spares from 4710C which was the airplane that was destroyed when with Dothan.
Chuckie still had some of the bracketry in the wing structure for the applicator "wings" and the holes where the poison was augered out to the applicators. The Myrex ant insecticide was mixed with ground corn cobs and loaded into a hopper in the radio room, then augured out to each wing. '543 still had some ground corn cobs up in the turtledeck when we worked on her.
