Dimensions:	4 1⁄8" H × 3 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.	H.G.CO. PATENT - OTHER

Insulator Overview

This neat insulator style was the first to sport Hemingray's patented drip points. In fact, some versions of this insulator have drip points on both the inner and outer skirts. Hemingray also made these for the North American Telegraph Company (N.A.T.Co.) between c.1895-1905. Officially, this style was known as Hemingray №22 in the, but no specimens exist embossed with this style number.

Known Embossings (24)

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.	Photo	Status✓ = In my collection If the value in this column says WANTED, then that specific insulator is on my wanted list!
