Here is a CD 154 (080) Hemingray-42 in hemi blue with a SMOOTH BASE. There are with three different bases - Flat, Rounded and Beveled. These are becoming more scarce as the main line they were used has been dismantled and the insulators taken to the dump. I have a few all three bases left in vnm condition. Price individually at $15 each plus shipping. Take two for $25 plus shipping. Take three for $30 plus shipping. Sorry, these insulators have found a new home!
