Description

#1580      U-376C      Unmarked.      Brown porcelain.

A large insulator measuring 5 inches by 4-1/2 inches.  Produced with a specially recessed pinhole, designed to accept a locking mechanism patented in 1901 by Harry Ethridge.

Only a limited number of these impressive insulators have been found, and they are seldom available for purchase.

The light area shown on the right ear is a thinly glazed area, not damage.  Has a little wear on the skirt surface.  Very old, shallow chip on the inside, near the pinhole.
