Forgot to post this one right after this previous photo: [id=244299993] This one shows two Hemi blue CD 1087 knobs marked: HEMINGRAY/107 // MADE IN U.S.A. Both of these insulators are Hemi blue, the one on the right has some surface haze which has made it appear much too dark in color. The one on the right is turned backward to show the reverse embossing.
