Insulator Facts

Dimensions:3 5⁄8" H × 2 1⁄2" W
Primary Embossings:The Primary Embossing is typically found on the front of the insulator and usually identifies either the manufacturer (such as "Hemingray") or the company that the insulator was made for (such as "AM.TEL.&TEL.CO.")

Insulators with No Name or No Embossing are denoted as such.
Years Produced: c.1871-1880s
Style Identifier:Hemingray often used style numbers, letters, words, or a combination to differentiate their insulator styles (such as: T.S., E2, № 1 Provo Type, Muncie Type, etc.) These are often, but not always, embossed on the insulator.

Insulator Overview

Two different styles of CD 104 were produced by Hemingray: the earliest are embossed with PATENT DEC. 19. 1871. This design was the first of several Hemingray styles to use the No.4 style number, later followed by CD 124.2, 124.3 and finally 124. This style was reassigned to CD 124.1 in 1999, but reassigned back to CD 104 in 2019.

The second style was manufactured for New England Telephone & Telegraph Co. Commonly manufactured by Brookfield, only a small number have been attributed to Hemingray. Note the sharp upper edge of the wire groove and the tight arc of the embossing.

Primary EmbossingThe Primary Embossing is typically found on the front of the insulator and usually identifies either the manufacturer (such as "Hemingray") or the company that the insulator was made for (such as "AM.TEL.&TEL.CO.")

Insulators with No Name or No Embossing are denoted as such.
EINThe Embossing Index Number (EIN) is a unique number assigned by the collecting hobby to each distinct embossing for an insulator design. It is normally shown in brackets, e.g. [050].
EmbossingMost common terms:
(F-Skirt): Front Skirt
(R-Skirt): Rear Skirt
/: New line of embossing
{}: Special note (not embossed on the insulator)
[#]: Represents a number

Other terms:
{MLOB}: Mold Line Over Base
(F-Crown): Front Crown
(R-Crown): Rear Crown
(F-Umbrella): Front Umbrella
(R-Umbrella): Rear Umbrella
BaseThe base is the bottom of the insulator. Hemingray made 4 different types of bases:

1. SDP: Sharp Drip Points
2. RDP: Round Drip Points
3. CB: Corrugated Base
4. SB: Smooth Base
Year AddedThis is the year that this embossing was officially recognized and added to the McDougald (1991-2008) or Briel (2011-2023) insulator price guides. It is not necessarily the year this embossing was discovered.
