This tiny but beautiful CD 500 Yellow Green glass insulator is from Uruguay and looks to be VNM+ shape. Has a few yellow amber threads swirling along the base/skirt area. This miniature insulator is about 2/3 the size of a pony! The saddle groove may be observed by turning the insulator 45 degrees.

First email gets this super piece that is not offered very much for only $35 plus postage. Thanks Rick!
