Alot has been said about verdigris on this list and mostly in reference to Steinways, it seems. Since I have only one Steinway owner among my customers (and it's a console) I haven't really followed those threads. (I follow the Kimball and Gulbransen threads from beginning to end!) Many have implied that the sluggish butts I have on my hands (boy, that doesn't sound very good, does it?) may be due to verdigris. How can I identify verdigris? The bushing is red, not discolored. The pin, when removed, does have a blackish ring where it was in contact with the bushing. The new pin doesn't move any freer than the old pin. CLP made little or no difference. Ron Koval has offered to lend me a set of reamers, but if it's verdigris, will reaming help? And will reaming the sluggish butts free them up indefinitely? I get the impression that the liquid solutions are only temporary, and I would prefer a permanent solution to this problem. (And all my other ones, too.) Tom Sivak
