Not having a patchbox sounds more like a Frontier to me.
See Frontier Gander's Hawken picture to compare:

The Frontier Carbine has a 24 inch barrel and a single trigger while the Frontier Rifle has a 28 inch barrel and a double trigger, and neither has a patchbox. Both have an adjustable rear sight which I can't say that the Mountain rifle would have.
The same smaller trigger guard are on both Frontiers which don't have the Hawken's finger hook.
This Frontier Carbine does have a lighter "honey" brown finish compared to my Frontier Rifle.
The Traditions nickeled barrels have a matte silver finish as in the picture that even coats the inside of the bore. It's slick but has a slightly grainy look to it. And the lock plate, hammer & drum are also nickeled.
Is this similar to the finish on your barrel and/or lock?
I believe that CVA also offered Frontier kits.
