Just a piece of advice, You should take these and try to export them and get them into the Source Engine. You can find some tutorials and documentation here: http://developer.valvesoftware.com/wiki/Category:Modeling
thats th point, pm me if you want the files, peeps wanted them a month ago when the unskinned version was up
