Revdoc, we see lots of Damascus samples, laminated samples, twist samples, then take these and multiply them by the number of various sources. It all gets confusing, but to my , admittedly engineering trained mind, it would be wonderful to have an article that showed all these barrels, from all the sources, side by side. Maybe you could do an article for DGJ or similar ? Now, I don't know if writing is your interest, but maybe someone could pick up this gauntlet and do a broadranging article with good photos from each era and source.
