Just uploaded a set of weathered U304(f) 2 & U304(f) 3 halftracks to GreenAsJade´s great site: http://cmmods.greenasjade.net/mods/5401/details
Please note that all versions of the u304 seem to share the same track texture (probably because of some file naming error?). So if you use this mod set, it will influence the tracks of all versions of the u304 halftracks. Also, the BMP´s for the u304(f) 2 are for some reason named u304(f) 7
Enjoy
