I bought what I think are square wire 2.0's approx 8-10 yrs ago. I can't remember the model exactly and I'm basing my deduction on images from google. They were bought from a reputable oakley dealer so I know they are genuine. They have a serial number on the arm under the unobtainium rubber and that serial is 71-906G. I am struggling to upload images at the moment as I'm on my stupid iphone. Is it possible to ID the from the serial?
