Do any original Hawkens or Lemans exist with 8 groove or radiused rifling?

Redheart,
 
I'm sorry it took so long to get back to you. I finally was able to use my son's camera and , don't you know, I took these photos and forgot to get one of the plug I cast. The plug just shows 7 groove, square bottomed rifling.










I don't know how to turn these around or enlarge them.I don't know much about this high tech stuff.
