Can anyone tell me what model my Oakley sunglasses are

[antgrey]

I've had these sunglasses a long time, probably 20 years. I got them from an Oakley service return, an upgrade for a returned pair of Oakleys that some nice fella had sat on. These Oakleys could do with some new sleeves, so I'd appreciate some help in tracking down what they are
