Taylor,
If you have Hanson's Hawken book, check the line drawings in it of the May rifle parts. I'll try to scan something sometime for you that will give you an idea how good a job you did on that gun. I did not mean to be critical about the tang. Its just a detail that not many pick up.
Chuck,
I did mention the Dunn rifle in my post above, but I personally think that is a replacement tag on that one. I think it was added to clean up the tang inlet when the barrel was set back and the old patent breech was removed. Its a great old rifle that still smells of dust, sage, buffalo grease, and blood.
On the discussion of Hawkens being slab-sided and ugly, I think the brothers were like anyone else. They put out some guns that were not-so-refined plodders and others that were highly refined and fine boned like an Arab stud. It was all a matter of who the customer was and what he wanted to pay.
