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.
