Here's a RARE porcelain dryspot insulator from Italy. Stamped (in Green ink): Verbano with a crown (in a triangle) 5-59. This cool insulator is unlisted in the books and the NIA website! I've had this in my collection for about 20 years and never seen another. Measures 3" wide x 3 3/4" tall. Has narrow 1" slice on a raised thread that is covered by the cap and a light glaze scratch (seen in pic).

First email gets this rare dryspot insulator for only $350 plus shipping. Thanks!
