CD 220, HEMINGRAY, Olive Amber
A style of insulator known as the saddle groove or Hi-top insulator produced for primary power distribution. Hemingray Glass Company of Muncie, Indiana produced these insulators from c1937- 1940's for primary power distribution with a voltage rating of 10,000 volts.
The CD 220 Hemingray-670 was the middle size in the "600 series," with the CD 221 Hemingray-680 the larger size, and the CD 218 and 219 Hemingray-660's the smaller sizes.
Until the discovery of 30 Hemingray-670's in the rarer colors of honey and olive amber found in Florida in a group for sale, most were dug up in the Hemingray dump in Muncie many years ago. This one in my collection is one of the insulators that were recently found in the group in Florida.
