Collectibles--General (Modern)/X1 brookfield
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.
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
