This is a CD 121 PAT'D SEPT 19TH 1899 (on dome) in a bluish aqua. It has a few small dings around the upper and lower wire groove ridge and a small area of wire groove rub. This damage is minor and as you can see by the photo, does not detract from the beauty of this one. It is a little better color than your typical plain old aqua. Sorry, you missed out! This insulator has a new home.
