It's a pretty okay piece.
To the author: Are you still around? I'd like to discuss with you on how to improve the article.
It could do with a picture. Any pic of a white baby grand piano, and just insert a caption of how it's freshly fed or something.
Maybe include a recovered note that may possibly hint to its origin.
You should still include test logs 1, 2, 3, 4 and 7. It's odd to see them missing - at least write them down and strikethrough them or something and say they've been expunged of data or whatnot.
