Vintage Burgler Alarm Panel? Mancave! Christmas Present! - $200 (Fenton)

Vintage Burgler Alarm Panel? Mancave! Christmas Present!!!- Manufactured by Holtzer Cabot Electric Boston Chicago New York Baltimore.
This would make a great stage prop or conversation piece for a mancave.
We believe that this panel came out of a bank in Chicago.
We were told that it was a control panel for a burgler alarm.
This we cannot substantiate.
Maybe other viewers can.
It measures 60 inches long and 42 inches in height.
The panel itself appears to be made out of solid granite, very heavy.
I imagine they used the granite for its insulation properties.
Cash Only.
