Dimensions:	3 1⁄2" H × 3 1⁄4" 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.1930s-1940s
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.	D-510
