In the early 1990's Marilyn Albers brought some unique U-2725 porcelain insulators back from England that were written up in CJOW (See February 1996) with a great two tone blue glaze! The one on the right matches that article -- the one on the left (assigned U-3079) is the only one like this I have seen! Both are in excellent condition. Figure $75 for the larger one and $55 for the smaller -- or take both for $120 plus actual postage.

Here is a snippet from the article:

"The particular U-2725 under suspicion was made by AI (Allied Insulators) Industrial Products Ltd. at their plant in Stoke-on-Trent, England. It stands 4-1/4" tall and has a skirt diameter of 5-5/8". The insulator is glazed a lovely soldier blue from the top of its crown down through the wire groove, where it meets a 1/2" band of pinky mauve, and then blends into a light blue gray from there on down to the base of the extended petticoat. Both front and side views of the insulator are shown below (how I wish you could see it in color!). In the second photo you can see the" A I" logo and the date of manufacture, indicated by the numbers 3-90, or March, 1990. AI came into being in 1959 with the merger of two older insulator manufacturers in England, Bullers Ltd. and Taylor, Tunnicliff & Co. Ltd. In addition to the U-2725, the company produces several other styles of low and high voltage insulators for telecommunications lines and electric railways. "
