Lot 167: CD 140 (Base) OAKMAN M'F'G CO. BOSTON.  Color: Blue  Description: 1 1/2" flake around a 1/2" factory bubble on the base, quite insignificant on the 6" insulator. The Oakman Manufacturing Company, which specialized in high voltage distribution insulators, produced CD 140 "Jumbo" insulators for the first underground trolley system in the United States. It was located in downtown Boston and service began around the year 1895. Most of the CD 140s in the hobby today were used on this line. A great piece of Boston transportation history!
