Probably my favorite insulator in my collection, this green Niner has no skirt at all, the threads "pouring" out of the base, distorting the drips and generally "creating mayhem with the enemy". The bluish 120's history is lost, but was traced back to a collector in Colorado, which seems entirely appropriate, given these were used in large quantities in the Kansas - Nebraska - Colorado area. A nice, heavy example with some nice seed bubbles to make things interesting.
