My sister found these Australian insulators for me. Any help with CD numbers and value would be greatly appreciated. The two pieces on the left side are C,C.G's and the two on right of center are A.G,M's. bothe the CCG's are fizzy straw in color. The AGM's are light olive green and light aqua. The center insulator is a dark gray color. All the taller pieces are 5 inches tall. They do have mold numbers on the rear sides.
