Here's a beautiful Violet Cobalt Blue glazed porcelain insulator from Ukraine. Unlisted in NIA website. Has a small factory circle on each side of the dome's wire groove. 2 1/2" wide x 3 1/4" tall. Similar to a U-1663 which comes in a white glaze from Vietnam.

Factory warped skirt is more oval than round! Excellent condition. No chips or cracks.

First email gets this scarce and colorful insulator for only $125 shipped. Never seen another one. Thanks!
