Here's a scarce unlisted porcelain insulator that has BOTH Manufacturas Ceramicas (Spain) and Vista Alegre (Portugal) manufacture markings! (Click zoom to read detailed incuse markings). Only seen one other.

Measures 4" wide x 3 5/8" Tall. Excellent condition with only a small pinhole thread chip and a few minor usage marks. Spot on lower skirt is factory unglazed area and not damage.

First email gets it for only $40 plus shipping. Thanks!
