Extremely rare CD 568.9 cobalt insulator from the Ukraine. There are less than 10 of these in existence and one of the coolest foreign pieces around. Although I really like this insulator it is my only foreign piece and I have decided to focus on North American glass so I am offering it here. Fantastic VNM+ condition with a tiny 1/8 inch base flake. Asking $1185.00 plus shipping and insurance. It may be a very long time before you see one of these offered again.
