Second edit: I just asked one of the other people that was there: 1880 was the first phase of construction. Given the following (original?) equipment in a house, how would you date the structure? We thought this might be a electromechanical call bell for the help. Edit: If anyone’s interested in a 800k-1M project house, this is a good candidate. I was just tagging along with some friends who were looking. It’s a really cool structure but needs 400k in interior and exterior work to correct deferred maintainance and modernize.

Radiator at the base of the main staircase. There were four other staircases in the house.
Coal burner in the sitting room. The original furnace was also present, and burned coal.
