Yes, it is the A.3dz which points to the SEX / SRA textures on the lead plane and SX / SRA on the secondary planes. I only sent the offending files on the first of the secondary planes (PLANE01). All the remaining planes are still using the primary skin so they will look correct, but it also means they have the same identifying letters as the lead plane.

Don't forget to check the other problem I described on Mike's 100 BG B-17 mixed silver, green and olive drab skins.. That is, zoom out as far as you can and pan side to side. You will see the green and olive drab planes turn silver as you go side to side.
