Here is a couple of CD 106 Birmingham's in straw. One on the left is (030) embossed. One on the right is a (020) unembossed. Both have minor wire groove rubs, but overall in very good condition and it would be hard to upgrade either one. These are not common insulators and you don't see them offered for sale too often. The manufacturer is unknown. Most believe they were made by Lynchburg, but no one is for sure. None have ever been found in Birmingham or anywhere else in Alabama. Price is $45 plus actual shipping on the embossed and $30 plus actual shipping on the unembossed. Take them both for $70 plus shipping. Sorry, these insulators have found a new home!
