Mr. Dudley acrylic salt mill

Mill for grinding salt crystals at the table. Elegant modern design in acrylic with a white plastic grinding mechanism. This one was bought in the 1990s but has been lightly used and is still in excellent condition with no scratches on the outside, some patina on the adjustment screw at the top (see photo of top). To fill, remove the top screw with a screwdriver and pull off the top section and the plastic connector. I don't think the grinder mechanism can be removed for cleaning. If you clean it by running warm water through it, as I did, be sure to allow all parts to dry completely before reassembling. 4.5" h x 2"w x 2"d
