I'm planning on trading this insulator for just about any other insulator with junk, amber or milk. The insulator for trade doesn't have to be in mint condition. This CD 152 Patented Hemingray No 40 with sharp drip points isn't. But before I traded this piece I wanted to know how common the embossing of this one is. It has a period both before and after Hemingray as can be seen in my pic. I'm calling it unlisted because all the price guide list are ones with periods associated around the No. 40. I am going to upload a close up pic and link it with the one on this page. If any of you Iconers out there knows about this embossing please contact me with any info. At the same time if your interested in a trade let me know that as well. Thank you for looking. [id=245668033]
