Nice condition overall. It does have some tool marks on the rear skirt and rear dome. These are not chips since they are actually dimples with raised edges and are not flush with the surface. It's my opinion that these marks were caused when the glass was still soft. A shallow 1/4" upper wire ridge chip just behind the right mold line, a 1/16" inch peck on the right side of the dome and a shallow 1/4" nibble on the far right lower wire ridge. Displays nearly mint. This is a VERY tough to find insulator. $175 includes shipping within the US. More photos available upon request. PayPal friends and family please.
