A "Servisignal" bell manufactured by the J.C. Adams Co. (JACO) of Rexdale Boulevard, Toronto. The bell is electrically powered, but triggered when a car runs over a pressurized rubber hose. From a day when this was a signal for "full service" when you pulled into a gas station.

Just picked one of these up at a yard sale.
I was disappointed when I took it apart.
the diaphragm was brittle and broken and the magnet was missing.
The diaphragm was an easy fix but the magnet was trial and error.
but I managed to combine mini magnets the correct diameter to actuate properly.
not much online about this brand.
This was the first site I stumbled upon.
What did you use a material for the diaphragm? Or were you able to purchase one?
