At one my time, a family member was employed in a water powered electricity producing plant.   This meter came from that plant many years ago.   It is made by James G. Biddle of Philadelphia, PA.    On the front it says Frequency Indicator  Frahm System    110 Volts.    The meter is 8 inches across the top, and 8-3/4 inches across the bottom and stands 4-5/8 inches tall.   The glass top is perfect.   The brass case is a bit discolored at different spots.   Tried to take pictures that cover all sides as well as top and bottom.   Questions gladly answered.
