I'm going to repost this great looking blue CD 267 embossed N. E. G. M. CO. and on the reverse side PATENTED. JUNE. 17 1890. It's the only cable I've recently posted that hasn't sold. It must be my fault because this is a very good looking insulator. The bonus with this insulator is a large 1" by 1 1/2" bubble right smack in the front where you can see it. Around on the reverse side there is another sizable bubble. There is an internal crack that travels along the base of the saddle groove. It does not reach the surface of the glass. There is a 1/4' sliver chip on the corner of the ear on the PATENTED side of the insulator. This really is a great insulator to add to your collection. It has been packed away since 1988, when it was liberated from the Boston elevated transit system and now it's waiting for you. $140 will get it delivered to you anywhere in the U.S.
