Like Todd says, I've never seen a complete world map model in a standard 3D format on a KF game disk nor anything like SoM's map Piece tiles. There are some flat tiles which the KF engine may build into the world map- not sure. The map textures are easy enough to get at.
I think it would be fairly easy to build a remake using the default SoM map Pieces. If you look at the KF(US) maps in the official KF2(US) strategy guide, you can see the exact dimensions of the maps and how their setup is identical to what SoM uses. I actually think those maps were made from screenshots of the KF developers tool. You can even see the tile coordinates along the borders just like SoM uses.
