[pianotech] Verdigris - again

[Peter Poole]

There must be hundreds of technicians that have dealt with verdigris; 
have they all seen it come back when replacing only the flanges? The 
only alternative would be to replace shanks and flanges; which means 
replacing hammers also, or popping off the old ones and regluing.

Best, Peter
