Trying to replace my kitchen sink drain strainer...

...but haven't been able to find it in the stores. Tried the big box stores and several local plumbing supply shops. The sink is a Kohler but the plumbers said they've never seen a Kohler strainer like this one! Hope the pic I attach can help someone identify the brand as it's pretty unusual looking....
Thanks!

you are probably better off replacing the whole assembly. Thy're not that expensive and are easy to change.
