12/28/20 - This is a ZF 4 scope with mounting rings, as shown in photos. The scope has exterior markings "Gw ZF 4", "dow", and "5464" serial number. The adjustment knobs appear to be functional. There is some light exterior patina, but overall the bluing on the scope is in great shape. No rust or pitting. The optics are poor with cloudiness throughout. Reticle is still visible and clear, however. The mounting rings are in great condition overall.
