It looks a great deal like my Centurion Super Elite in terms of derailleurs, frame chrome and the like. It has had its foil decals on the down tube and seat tube removed, if it was like mine, and either repainted or just stripped of the foil stickers on the seat tube including the one stating that it is made of butted Champion #2. I lean toward a repaint, since the identifying top tube script saying "Super Elite" on mine is in faint gold cursive that appears to be hand painted. I don't think it came with the barcons. Mine was basically mint, came with the original owner manual and suntour "power" ratchet shifters on the downtube, but it would have been an easy convert. I think it's one of the best looking bikes from the period, and I love how stiff the frame is compared to my early 70s Bob Jackson Messina frame. Also the Pro-Am hubs are arguably smoother than the Campys they copy. Do you have a link for the way you found to decode year from a Centurion serial number? I stilll don't know the exact year of mine, but serial number starts with M7E. Thanks!
