Can't find the Crit-a-Cola model?

[MarMar]

I've looked through every TF2 weapon file in the Games section and I can't find it.
I've searched for it, found no results.
Then I thought, "It must be a reskin!".
And then I found out there's no skin switcher addons in the workshop so far.
So, I need help either finding a skin switcher that works with GMod 13 or finding the crit-a-cola model.
Thanks.
