Robert and Miller have shared some valuable knowledge. I certainly appreciate the information. They describe a very different approach from the billet method. Possibly one that has older roots in the eastern roots of welded damascus. I think it would be safe to assume that the billet method was a later development. There are examples from circa 1700 India where a type of billet was certainly used.
The Belgians relied heavily on rolling mills. They even used the history of their rolling mills to trace the development of the damascus barrel industry. Noting carefully when and where such mills were established.
Certainly the English had as many rolling mills, perhaps more. It was all part of the developing industrialization that was taking place across Europe and America. The English also used the billet method as the barrels plainly show.
So in keeping on topic with this thread. Of the existent American examples of welded damascus. Was there a dominant type? Stub vs billet so to speak. Are there examples of American produced crolle?
