I believe Renegades had 26" barrels vs the Hawkens 28" barrel, and all blued steel furniture, as well as a flat, shotgun type butt. The Renegades also didnt have a cheekpiece on the stock.
If you google images of each you should be able to start recognizing the differences.
FWIW, the Hawken looks more old time with the crescent butt, but Ive come to like the flat type butt quite a lot more for fitting me and general handlng and shooting. The TC Hawken crescent isnt as hard to work for me as many traditional crescent butts, but its still not as easy to shoulder and comfortable to me, as the flat type.
