Hey Everyone, New member here and big time Oakley sunglasses fan! Just scored an incredible deal, I picked up a pair of chrome Pro M Frames with a sweep lens in incredible condition given the age (just missing a little paint on one of the icons). I was wondering if anyone could tell me how many...

Most of my m frame lenses have a date in them. Usually something like 031804. I have one lens that says NT1. Does anyone know what that means? Thank you.
