Can you identify?

Looking for identification or information on the insulator on the left. I have been looking for things on the internet but can find anything. So I figured I would turn to the collectors here. Any help would be greatly appreciated.

Here is a response from a buddy who collects insulators

The one on the left is a porcelain neon light insulator and the glass in a CD 115 exchange. Both are worth about $5 each.
