Hemingray - 830
Insulator Facts

Dimensions:4 1⁄4" H × 5 5⁄8" 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: 1951-c.1957
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

This later high voltage power insulator was one of the last styles produced with the Hemingray name in 1951 before they rebranded them as Kimble insulators. As such, these are much more commonly found with the Kimble embossing. The Hemingray embossed versions are very underrated in my opinion. This style was the largest of the 800 series power insulators produced, dwarfed only by the experimental CD 239.2 Kimble 850-1.

Known Embossings (4)
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 (4)

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.
