Getting 1.5 Character Models to work in 1.6 ?

[Psycho021]

Heres my question: A few of my friends have 1.5 Character Models, while alot of us have the CZ Character models, I do not have Condition Zero, and yet I still have the models, so I was woundering if anybody could help me get the 1.5 character models back, and have it so it works in 1.6 STEAM

Okay thanks..
