The TF2 Basic Weapons pack currently uses Azerath's Pistol model (which I don't have permission to release...) and some of Racer's models which appear to have no animations at all and look quite bad.
The Ambassador uses a model which I can't figure out how to get to animate and is a bit large, so I'm not releasing that one yet. It's also quite overpowered.
The Medic pack is currently broken as of v13 and I haven't got around to fixing it yet.
