Vintage

/ Spring adjuster
Used in adjusting the 0.030 inch spring tangs next to the core on UA-type relays . Handle is insulated .
Telephone Phone Repair Tool
Comes from an ex repairman.
Most of the tools he had were marked WE / Western Electric & a bunch were BELL System.
All have been very well cared for. Protected from the elements and not abused.
I will often use the Northern Electric tool catalog page to show a description of the tool.
This catalog was the most extensive I could find and has the same tools common to all areas.
