Antique Large Weston Electrical DC Volts Gauge Model 24 Railroad meter 6.5”

You get Weston Electrical Instruments Co. Model #24.  Item shows obvious wear, scratches/scuffs at edges.  No idea if it works. Last patented in 1901 based on label.  The face of the gauge is 6.5” in diameter, the base is shy of 7.5” diameter.  From the front to the back it is just shy of 4 inches deep.  The connectors on the back stick out 3 inches. Please ask questions if needed.  Due to its fragility and weight, it will be shipped in a box inside a second box.
