CD 155 (skirt) KERR DP1 // MADE IN U.S.A. 14 78, smooth base, clear color, 3/4" crack in the back that you can't see when looking straight on. As you turn the insulator, you can see th crack. It almost looks like an annealing crack. Otherwise mint. I can't feel it with my fingernail. You can see it on the right side of the insulator in the picture. I tried to take a closeup but it kept coming out blurry. $165 postpaid.
