Antique Short & Mason Octagonal Tycos Wall Barometer. Barometer weighs 59.5 ounces and is 9 3/16″ in diameter and just under 1 7/8″ thick at the edge. There are scratches around the hanger and on the bottom facet. It has been tracking changes in pressure and now reads 30.26 (against 30.15 on my barometer/altimeter). There is an adjustment screw on the back, which I have not used. Altimeter in last photo for reference, not included.
