CD 295
Hemingray №72
  • [085] Tall Variant
    This variant has an extended outer skirt which makes it 1/2" taller than normal. This only appears with the [085] embossing.
  • 72.A Wide Groove Variant
    This wide groove mold variant has a wider saddle groove to accomodate a larger wire. These wide groove styles are all denoted by the "A" appended to the end of the style number.
Insulator Facts

Dimensions:4" H × 4 3⁄4" W
Primary Embossing: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.
 HEMINGRAY
Years Produced: c.1900s-1930s
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

This high voltage style is identical to the CD 237 in every respect except that this style has three petticoats instead of two, and therefore has a higher voltage rating. Originally the №4 High Voltage, it was later renumbered to №72. A wide groove version was also later made to accommodate larger wires (denoted by the "72.A" style number.

Known Embossings (11)
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.
