#3165-C CD 257 HEMINGRAY PATENT JUNE 17 1890 MAY 2 1893 Green and aqua with olive amber impurities.
The various designs of Hemingray insulators are often different from what other manufacturers produced. Numerous other glass houses produced a standard "saddle groove" insulator for high voltage, most manufacturing the CD 258 though 260 "helmet" designs, whereas Hemingray created a completely differing design, the CD 257 "Mickey Mouse" type.
Typically found in aqua and Hemingray blue, the "green mix" units are scarcer, and in high demand by collectors.
Predominantly green with swaths of aqua in the ear tips, and a generous portion of olive amber swirls, having most notable separation in the ears.
Two drip points in the front have open bubbles. Sizable flat chip on reverse of one ear.... see small white dots on right ear in second photo, which outlines the perimeter of the chip.
Update 10:05 A.M. Saturday, July 8: Third image added showing the very shallow chip to the right ear. The entire flake-like chip stays very close to the surface. When viewed straight on, it's nearly non-detectable.
