Description

Nice  Western Electric telephone ringer bias springs. Use on 634 ,534 and 334 subsets  ...653 and 553 wall phones.
These were made custom for us by a professional spring shop to exact specifications. The same wire thickness the same amount of coils and the exact same tension. While they may not be original they are 100 percent exact in every way. Why use pen springs or other springs sold on eBay, when these work so much better.
Very easy to tie on.
Stock up on these as original ones are hard to find.
Most are missing.
