What Are These M Frames?

[loganre17]

Picked these up today and know nothing about them. Anyone have insight on what exact model these M Frames are?

The frames do have some cracks in them, any ways I could fix them as best as possible?

1st or 2nd gen M-Frame with sweep lens. @Rustpot could tell you more exact for sure. NIce pick-up regardless.

Maybe 1st gen since they have "OAKLEY" on the stems instead of the ellipse "O"

Looks like blue iridium installed too.

Thanks guys, what would be the best way to reinforce the cracking frames?
