Here's an uncommon U-1361 porcelain insulator with markings identifying it was made by Porcelanas Giralt, S.A. (Unlisted!) in Spain. Most of these are unmarked but were identified with paper labels similar to Manufacturas Ceramicas production method. This style was made by at least three different manufacturers. There is a creamy blonde glaze example from Portugal. Measures 3 3/8" X 3 3/4".

This one is in fabulous mint condition with a drippy glaze base. First email gets this heavily factory marked example (manufacturer, catalog number and date) for only $50 plus shipping. Thanks
