Photo taken along historic Main Street in Hingham, MA. The top crossarm with two insulators belonged to the Hingham Light Plant and carried either a series street lighting circuit or primary voltage lines (likely 1,100 volts) for their lighting customers. A six-pin crossarm with New England Telephone & Telegraph Co. stenciling is immediately beneath on this octagonal, pencil-topped pole. The trolley mast arms along with their wires often were mounted on the Light Plant's poles with an annual charge for pole-space usage. The town's trolley system began around 1898 and continued until the late 1920s. Some of the re-usable insulators from their system upon dismantling were employed on the Hingham Light system, notably old porcelain, dry-process, deep-groove side-tie pintypes from around the 1910. Most of these had nicely speckled glazes and likely were from the Trenton, New Jersey potteries that made dry process porcelain. Many survived through the later 1980s and early 1990s when the town entirely upgraded itheir electrical distribution system.
