We're now up to album #35 and I seriously need professional help
http://www.picturetrail.com/gallery/view?p=999&gid=18015717 I've posted the pics from Ross and Doug. I agree with Doug that we're probably looking at the end of individual 'strands' of wire which were braided, then twisted around the mandrel.

So gentlemen: please check your damascus barrels for odd patterns, flaws, etc., take ultra-close-up pics like those posted, and send by jpg attachment to revdoc2@cox.net and thanks!
BTW: what would you give for a time machine that enabled us to visit
E. Heuse-Lemoine in Nessonvaux (and speak French) and talk damascus barrel production with one of the workmen?! I don't want to give away too much, but Pete M may have found one!! More to follow.
