I put up several .psd files containing historically accurate layers (as best I could make them, at least) for the group markings used on B-24s from all the USAAF groups that operated them in combat. Please note that these are only markings layers and not complete templates. These layers will work with any B-24 template you might have, just copy and paste them in.

Some examples:
90th BG

380th BG (middle war version)

307th BG

308th BG

15th AF groups (HiVis)

8th AF (early)

8th AF (OD HiVis)

8th AF (HiVis)


All in all, a lot of layers. There's 49 layers just for the PTO/CBI groups (I didn't count how many MTO or ETO layers).

Enjoy them and please put them to good use!
