Description

#2771        Underarm Type Insulator.       White porcelain.

Insulator height: 5-3/4 inches.  Overall height with pin: 9-1/2 inches.

From Great Britain.  Once part of Keith Neal's collection, later purchased by Marilyn Albers after Keith's passing, and still later became a part of the Jim & Lis Bergman collection after Marilyn passed.

This insulator is shown on page 69 as Figure 95 in Keith Neal's book titled Searching For Railway Telegraph Insulators.  He describes it as "Later heavy porcelain insulator with 5/8" bolt.  Unmarked. c 1870."

The flared umbrella at the top was designed to shed moisture, thus protecting the lower portion of the insulator.  Buller, Jobson & Company illustrated a similar type insulator as part of their inventory, classifying it as "E.I. 467."

There's actually a shallow chip on the bottom portion of the umbrella that has been glazed over!  Obviously done at the factory.....  it's interesting to see with glaze overcoat!

Very near mint.

From the Bergman collection.
