Design ID
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].

(F-Skirt): Front Skirt
