Up for bid is a Locke A Electrical Insulator.  This one has variations of a brown glaze.  It measures 3.5 inches tall and approximately 3.75 inches in diameter, and weighs in at slightly over 1 pound 7 ounces.  The last photo shows a small chip on the base.  You can also see in the fourth picture that the base that screws onto the pin is a wee off kilter instead of a perfect circle.  This will be shipped by USPS Ground.  There is no reserve on this auction, so it will go to the highest bidder!  Thanks for checking it out.
