I recently acquired a couple Faraday 10123-1 pulls several years after ruining my first one from losing the reset tool. However, when they arrived I noticed some differences between my old one and new ones. Namely, the locks were made of plastic instead of metal. For this thread, I am using the plastic lock pull that is in better shape for comparison
I also found information on them from this pdf from firealarmresources that showed a metal lock, and a circled logo. Below is a comparison between my pulls and the PDF
One thing that comes to mind is the possibility the lock was changed to plastic due to it being able to strip should the wrong tool be used (see the metal lock version of mine).
Additionally, I noticed that the catalog listed presignal variants which had different model numbers
Knowing he had one, I asked VintageVibratone for some pictures of it.
As you can see, it has the older circled logo, a metal lock, and a springloaded breakrod retainer. It very much resembles the brochure
This leads me to believe that there are three generations of these. Any other information or new designs to share would be appreciated.
