In case you're not keeping up with pianotech, Kit is found on utube (per Terry Ferrell) at http://video.on.nytimes.com/index.jsp?fr_story=51447a22df4808817b10c4ec7f31af913673f701(I've not seen it).Other email guessed how it works, but I'm a bit busy now to comment onit, or refer to the Journal article (I don't remember which issue itwas in).Hope your summer is good.Mark----- Original Message -----From: "David Boyce" <David at piano.plus.com>To: "Pianotech List" <pianotech at ptg.org>Sent: Sunday, July 15, 2007 4:36 PMSubject: Re: Steinway double-keyboard piano> How interesting to see this instrument restored!
