I bought a pair of Ducati Juliets on ThiefBay and just got them in. I also own an old pair of Ducs. I know Oakley stopped serializing them at some point (my old ones are DUCATI0297) but these ones I just bought dont say anything. The arms are completely blank. I thought Oakley always put the model number on the arms. The seller claims to "know nothing about these" and says they are from an "Estate Sale".
