Greetings Mr Berry.  I am trying to find a value for a Brookfield X1 insulator. It appears to be unused if that impacts the value. Any information you can provide would be greatly appreciated! The images I attached were taken in front of my screen to help pull out the details but if this isn't helpful, please let me know.

Answer
Hi Ruthie,

We identify your insulator as a CD 102.  Insulator collectors have developed a numbering system for the various styles.  I'd date this from the early 1900s.  Brookfield was based out of Old Bridge, NJ and was in business from the 1860's through 1922.  I suspect that your insulator was used but sustained no damage in use (not too unusual for these rugged glass pieces) -- we would classify a piece like this as being in mint condition (no damage).  These are pretty common as they were used by the millions so do not have a high collector value - figure $2 or so.  These are still great pieces of communication history being well over 100 years old!  The X1 on the dome is a mold number - these were used to track production. Hope this helps

         Thanks, --Bob
