Ornate Seth Thomas Schoolhouse regulator clock pendulum. From top to bottom of the rod it measure 7 1/8 in in length. The entire pendulum weighs 4.5 oz. At some point someone added a bar of steel to the original pendulum to lengthen it. They just attached an additional piece of metal with a screw and a nut. So the pendulum can easily be shortened again to a length of 6.5".
