Hi All,  Craig Brougher has written an article titled "How to Sell
a Player Piano". A fair portion of the article focuses on rotting
valve leather; why it happens and the inevitable results. He also
shares his viewpoints on what pianos and player pianos have
historically represented.

I found the article interesting and informative. It is now posted at

Musically,
