1950’s Optometric eye tester that is in nice smooth working order. Lenses turn, dials flip for augmenting magnification. If you wear glasses you are familiar with this device where the doctor goes this or this while you are looking at the tiny letters and can’t decide which is sharper. The older models like this one are great looking objects and this one comes with a nice custom stand ready for display. Measures: 14” H x 13” W on a 6” x 6” base
