We were fortunate to be able to see this amazing time piece in the tower of a church we recently inspected.
The church was built in 1829 but a little research shows the E Howard company was formed around 1842 in Boston. The bell was stamped 1853.
This mechanize kept time on the clocks in the church tower and every one was accurate. As you can see it is spotless. A couple of toothbrushes and a rag were in the corner for regular cleaning.
The pendulum swung from it’s mount through the floor, it was amazing to see this still operating, just clicking away up inside the steeple.
