Wolfenstein 2009 model extraction

Has anyone gotten any luck with this? A bunch of character models were taken from that game and I was trying to get the weapons out, but I cannot figure out how.
Extracting the psk files wields mostly just textures and some weird “md5r” files, which I presume to be animations.
I have looked everywhere, but I could not find an answer.
If anyone knows anything, please tell. NinjaRipper is too problematic and 3dripper too crude for this situation.
