Only in the last year have I got into collecting Oakley's, and every collection needs something X-metal. I work at a car dealership and these were found in a car that was traded in, The guy who cleaned it knew I was an Oakley fan and gave them to me. $40 for a tune up from Oakley and they are almost perfect once again. The lenses are totally shot, but the serial number is J002676. I'm wondering if anyone can tell me when these were made. thanks !
