Hey… My server is using the model
[Lua]
models/weapons/w_fists.mdl
[/lua]
To the hands and keys. but the problem is that the server / and me dont have them. after i had reinstaller my garrysmod it just didnt worked…
So i would be happy if you guys could help me by telling me where the location are, or give me a dl link for it 
I got it fixed. i joined the VM (Ventmob), and they gave me the mdl file and so on
