Hmmmm its just too random for my liking , must take a close look at my Zero arms . It really is like a Friday afternoon on the assembly line after the pub , lets just stick anything on anywhere !!!! Bit like those sub zero fingerprint N's that just appeared out of nowhere , mind you they did have a box with a code !!!
Ah Paul , you are probably only used to seeing them brand new in the box not having been out being used in the real world for 25 years the frames match all my other Gen 1s apart from this odd stamp.
Going back to page 3 and Dann's excellent breakdown of Gen 1 & 2 M Frames lenses and the date of issue , has anyone got or even seen a picture of a Gold Iridium Gen 1 lens in any model. This will be a lens without Oakley on it.
