This antique piece of technology was produced by Western Electric in the early 1900s. With a DC motor and distributor, it is a rare find for collectors of vintage telephones and electronics. The item was manufactured in the United States and is a testament to the ingenuity of early 20th-century technology. It would make a great addition to any collection of pre-1940s radio, phonograph, TV, or phone memorabilia. I think it was used in a central office to put talk voltage on the old phone lines
