Though this is not a CD 135 Chicago Ins. Co. my specialty type of insulator it is a Chicago Insulating Company type and it fits in with the Diamond grooves I have. I am having trouble trying to find CD 135's to add to my collection so this was a more recent addition.

It has some nice milky swirls in it with a glob of snot that adds to its attraction. I was able to get this great example from Robert Baumann a while back. He is a great guy to get hard to find insulators from and gives very good deals.

Thanks Robert.
