Wanted: Sea & Sea 82mm Correction Filter

Looking for a Sea & Sea 82mm Correction Filter for my Sony 16-35 f/2.8

Let me know if you’ve got one and may sell it. 
Thanks!

I looked for one for several months before I bought one new at Reef Photo for $600.

A brand new one is out of my budget for now, so I’m hoping to get a used one if possible
