I am on the phone right now, i will answer from memory.
1) Coalition cruiser
2) Yes
3) I think it's an LSF experimental cruiser, I'm not sure
4) The short one is the carrier prototype, the long one is the bretonian carrier available to players
5) I'm surprised i didn't forget more, milkshape can't open some files from discovery, it's a convulted mess with numerous cmp types, each made however the modeller saw fit
6) Could be, i added both council and grn variants because i don't know if they differ in any way other than the texturing.
