I have a yearbook for class 44A from La Junta, and it has a photo that shows one converted B-25G used as a trainer. All the other B-25's appear to be B's, C's and D's. The planes all have a J field code, followed by the last three digits of their serial number painted on both sides of their noses. Most of the planes shown have had their top turrets removed, but not all. All of the planes in this book are still fully painted, no shiny silver ones here yet.
