mystery

I have had Oakley's and only Oakley's going back at least twenty years. I found these lenses and they don't seem to go to any of my glasses and they only pair that I can recall ever losing was a pair of Flak Jackets but I have other pairs of Flak Jackets and they don't fit them. I am wondering...

Hey Oakley Enthusiasts, I have a pair fairly well constructed "Oakleys," but I don't know what kind they are. They look like a pair of Fives but they have four screws in the frame to replace the lenses. They are half matte black around the lenses then the rest of them are a dark Crystal...
