Can't Find SN - Need Help

[wheresaxl1993]

I have a couple pairs of these Oakley's that were part of an estate I'm liquidating. They look like radars, but they are not. Can anyone please help me identify them.
Thank you-

Not Radars. They're older M Frames (maybe Gen 2) specifically the ones made for baseball (because of the straight arms)

Got more pics of the other pairs?
