Not much, but there is a small chance that they are seam welded tubes of (hot rolled) mild steel; which is really a form of fluid compressed steel, just not alloyed, sized, shaped, or intended for barrels. Think about it for a minute. There was no reason to have fluid compressed steel pose as damascus. There might be a reason to have seam welded mild steel tubes faux painted to hide the weld. Posing as damascus is not illogical and more plausable than trying to pass painted barrels as blued/blacked steel barrels.
