Ok, the tanks are all showing in the list ok, the aircraft is able to carry them ok, however we still have a couple of problems.
A) They're not actually visible (a model problem I suspect ).
B) I've assigned a grey tank to one wing, and a desert tank on the other in the Jaguar's ini file. Instead of all tanks being available for all FT enabled stations, only the assigned ones show as available, in other words I can only load a desert tank to the left wing, and a grey one to the right and don't have a choice of tanks (hope that makes sense).
The new variations had already been set up as you suggested, for example the desert tanks details:
Folder name = Tank_NADR_Desert
Model name (LOD file) = NADRUK
Data.ini file = Tank_NADR_Desert_data
Config file = TANK_NADR_Desert
Bmp name = NADRUK_Desert
OUT file = NADRUK_Desert

Thanks for the help so far, it's much appreciated.
