Here's an unlisted snow white porcelain insulator with a cool blue stripe! Marked with K in a circle and 44 (probably made in 1944). From Japan.

Measures 2 5/8" wide x 4 3/8" tall. Not found in the books or NIA website. VNM+ condition: (light use marks, tiny wire groove flake and very tiny nicks).

First email gets it for only $100 with FREE shipping (U.S.). Split shipping to Canada. Thanks!
