Lot 152: CD 140 OAKMAN MFG.CO. [030]  Color: Blue  Description: This massive power piece weighs nearly 4 1/2 pounds and its coloration is a beautiful Blue! This example is somewhat unusual in that it has a lot of "junk" in it, especially in the rear where one can see many impurities and several 3/8" bubbles. Note this is the less common embossing with "JUMBO" and "PATD JUNE 17, 1890, AUG 19, 1890" on the skirt and "OAKMAN M'F'G.CO. BOSTON" on the base. All the embossing is bold and strong. 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. Service began in downtown Boston around the year 1895. Most of the CD 140s in the hobby today were used on this line. Fantastic condition, especially considering the size of this insulator! Between the embossing, the character, the color, and the condition, this Jumbo is worth a premium and certainly worthy of a spot in your collection!
