I just unpacked a vintage frameset and was trying to figure out what it is. It's got a columbus sticker that doesn't tell me enough and chrome forks. Any way to tell tubing apart from the butting? It's got a race number-hanger on the top tube and a nice red whit and blue fade job that makes me think it might be an old team training bike (the frame was sent from france). The levers are also drilled. Any way to reference the serial?
