The CVA Hawken is one of the nicer mass produced rifles. You have a good find that you will enjoy. I saw a well used one at a LGS not long ago and passed on it because of it's neglected bore. I do not believe that these guns are still being produced by CVA. I have my eye out for a good used Lyman Great Plains rifle. It is the Hawken style with steel rather than brass furniture.
I still have one of those CVA .50 Hawken rifles kicking around. I picked it up back in the day brand new for around 100 bucks. It's been a fun rifle to shoot over the years. I also have a CVA clone of the .44 Colt Walker Revolver. Last I heard CVA was only making in-line percussion rifles, and I don't think it's the same CVA that used to be out of Norcross, Georgia where both my coal burners were from..
