Hi. Just acquired a pair of Carbon Juliets w/Blk Iridium Polarized. Lenses are in near perfect condition, but the frame is a bit... worn. So... First, I noticed that the frame has no serial or model number (I've had Juliets before. One pair had a serial, the other didn't), is this normal as I've heard that some generations don't have a serial/model number. Second, the entire nose section is extremely loose. Is this something that I can fix myself or do they need to go to someone who can fix this (or go to Oakley), and if they do need to go to someone, does anyone have recommendations? Lastly, the frame is a bit scuffed on the top of the frames above the lenses, but it appears to be badly pitted (could even be classified as dinged) on the front of the frame above the lens. Logic tells me that this is something that can't be fixed without completely stripping and redoing he entire frame. Am I correct in this thinking? It's not THAT important as I will be keeping and wearing these, but tightening up the frame is important to me. Any advice, help and/or info would be greatly appreciated and thank you all so much for the great discussions.
