[pianotech] WNG jack don't come back no more, no more, no more.....

[Ed Foote]

I have an early WNG kit, and the springs are steel colored. Damn strong to begin with, too!

Renner springs are pure beryllium copper.  Are these WNG springs by 
chance plated to look like beryllium copper on the outside but 
something harder like steel on the inside?
