Hemingray №12
  • Early Script Style
    This is the earliest style mold with the script embossing style. Note the rounded dome and thinner, rounded wire groove lips.
  • Prismatic Style
    Before the modern stamped style and after the script style embossing was the prismatic style embossed mold, shown here. This particular mold is slimmer with more shallow wire grooves.
  • Tapered Mold
    Beginning in 1941, Hemingray switched to this style. This was the last style produced. Note the larger lower wire ridge that tapers down to the lower wire groove.
Insulator Facts

Dimensions:3 1⁄2" H × 2 3⁄8" 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.1890s-1940s
Style Identifiers: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

The No.12 was a very popular pony style, and can commonly be found in aqua and clear colors. As a telephone exchange insulator, the upper wire groove held the line, and the lower wire groove supplied the drop wire to the house.
Known Embossings (43)
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.

Removed Embossings (3)

The following embossing(s) were removed from the price guide because they could not be verified to exist, were consolidated with other embossings, or were otherwise ambiguous/inaccurate. They are preserved here for historical purposes.

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].
