Another enthusiast discovered this odd looking siren in Talbotville, Ontario on top of the fire station. It's wired up and on a very weird mount, and is inside of a strange custom housing with the chopper(?) on top inside the housing, and a thing on the bottom to direct the sound. Its design is incredibly similar to an electronic railroad crossing bell, but far larger. Does anyone have any clue what this could be? Photos were not taken by me.
