These are using the thin stretch elliptical O logo so I can guess they're pretty old, but I've scoured the net and this site, and haven't been able to find a visual match. The model number is OA5006.

Thanks Marcellus. Would you mind sharing a bit more? This was passed down to me by an older family friend, that's quite unfortunate.

As stated, these are fakes

The first thing to start with is that the SKU number is not an Oakley Sku number and does not fall into the standard Oakley format. Which is why you cant find it.

Second, they never etched "Oakley" on the lens of any model as its shown here. Across the nose bridge of a shield lens, yes, but not in the corner of lens like this.

Third, That Hinge style never existed in any Oakley model. For what this is supposed to be, it would have snap off arms.

Fourth, The way the nose pieces are mounted is not accurate to the Oakley model that its faking. Wires frames nose bombs mount in a vaguely similar way, but these are completely wrong.

With the way the arms are shaped I'd guess this is a really bad knockoff of a Flak 1.0

Thanks Micah, appreciate your taking the time to type a detailed response, that was an informative read. Off to the bin they go!
