These are pretty rare and pop up occasionally. I actually have both the ZF 500 and 800, not interested in selling. They are nice scopes for the time they were made. I would also suggest checking gunbroker often and doing a google search often.
Just to clarify you are looking for a ZF 500 or 800? The ZF 84 and 85 are Kahles scopes which is the military side of Swarovski.
IEA Mil-Optics will import optics that are surplus. They are one of the best places to find older scopes that are no longer made. You can e-mail them and they will let you know if they have a model you are looking for.
