The pattern looks the same to me just "tighter". I think it's just an example of a "better barrel".
Check out the pics of the Blisset....the Damascus pattern tightend up on it. I don't own the Blisset anymore so I can't post pics of what I'm talking about. The Damascus pattern matched to a tee on both barrels.
What I see in the picture at the top of this page...is a barrel made by a less experienced barrel maker. That "anomalie" no doubt left the shop like that.
The best barrel makers made the best barrels and they went on the higher grade guns.
