[CAUT] Steinway verdigris

[David Love]

But are they 60% copper at the point of contact?

Hi, David

Ron N. pointed out that nickel silver (German silver) is 60% copper. So 
using them would not keep the bushings from contacting copper.

What I still don't understand is why brass center pins have been 
replaced with nickel silver in the first place, and what merits they 
might have.
