Talked to a guy that said he had some insulators and would bring them to the flea market for us to look at. He told me that they were not all Hemingray 42's. We were happy to find out he didn't have any Hemi. 42's, 40's, 9's or 12's. The first 2 are CD 121.4 A.U.'s. ! is aqua with some amber and the other is a nice light green full of bubbles with some amber .
