Stuck in a script for character models

[Raven's Fantasy]

I'm stuck in a problem so let me start from the beginning , simple and small

This is about my Cod4 promod 216 live raw which I'm using for my promod snd server , I'm posting this here cause there is no other place in the internet better than here about the topic I'm talking about.

I wanted to add a few character model for my cod4 promod server. I've put all the files perfectly in images/materials/material_properties/xmodel/xmodelparts/xmodelsurfs , precatched em and edited the mod.csv and compiled it. Since I didn't knew what's the code to select the skin in game , I opened a zombie mod source to read its code to select skins. Here's what I found out

main()
{
self setModel("anna");
self setViewmodel("viewhands_tf141");
self.voice = "russian";
self.armor = "light";
}

precache()
{
precacheModel("anna");
precacheModel("viewhands_tf141");
}

and another one

main()
{
self setModel("Nyreen_ME3");
self setViewmodel("viewhands_tf141");
self.voice = "russian";
self.armor = "none";
}

precache()
{
precacheModel("Nyreen_ME3");
precacheModel("viewhands_tf141");
}

As you can see , there is a Viewmodel named viewhands_tf141 in both main and precache. I don't understand what is this viewhands_tf141 ? there is no viewhands_tf141 in my mod source and all I could guess is that since Zombie always makes the players select on one side of the team and the other one is for zombies, maybe viewhands_tf141 means only the team of the players can get the models , not the zombies. So what should I actually put here for setViewmodel and precacheModel ?

Thank you for your patience and time for reading out my problem. Hope you'll help out this fellow person.
