I have an AR barrel that I bought about a year ago. It was used but unfired so there is no paperwork with it, and I can't find the email trail with the buyer. I don't remember if it was a Douglas or WOA. Is there anyway to tell the difference? The only markings are a "35" up near the collar and "CLE 1-7 4-09" at the top of the barrel. Not sure about the 35 and CLE, but I believe the rest is twist and the type of SS.
