Insulator on left is a CD 423 embossed A.G.M. 27 - back 5::::: in a straw color appears like a small crack in pinhole looking down from top but only surface cracks inside does not penetrate up in glass - I'm asking $15 plus actual postage. The second is a CD 423 embossed C.C.G. but is faint and comes in a lite purple tint. It has a slight crack at base at mold line that extends about a 1/4" - I did not notice it the first time I looked at insulator. I'm asking $50 plus actual postage.
