Here's a an uncommon insulator that was made by Sediver for use in Chile. This style insulator is on display at the Sediver museum in France. Embossed: EIV (front) with the large "S" sandblasted on the (reverse) skirt indicating it was used during WWII. Also 09/U-15 (reverse skirt). 4 pinhead sized tic marks from mint!

First email gets this hard to find insulator for only $100 plus shipping. Thanks!
