Then to make it easier, get the Freelancer Mod kit from ModDB, has HardCMP, which allows you to view the models. Also has some texture programs with it. After getting it, you need to find the file, it should have the prefix Brand than the number, unless it was a custom.
Thats what I thought....that ship is part of the Discovery Mod, and not an original Bretonian ship. You have to have the original Freelancer game to load the Discovery Mod.
