What we have here is a A/O American Optical Lensometer. Somewhat below mint condition due to scratches on body but in great condition as noted in pictures posted. Purchased from an optical that was closing over a year ago. Please look at pictures for all the details for this work of art. It does turn on and everything seems to be in working condition. One of my favorite in my collection because of the ridicule inside displays power. Condition is used as obviously mentioned but still in great working condition. Hate to part ways with this piece as I’m a collector of lensometers but I need some space back in my optical. Happy Bidding and good luck! Shipped with USPS only and buyer pays for shipping. Also follow and stay tuned will be putting more antique lensometers up for bid in the coming weeks.
