Bill,

Thank you for your sincere interest in the Duplex Scale tuning procedure. 
Contrary to your position that people are losing interest, I have found that 
technicians seriously interested in piano tone are gaining substantial 
interest and technical knowledge in how to deal with the subject. The number 
of new pianos with duplex scales and the improvements of  duplexes in 
existing pianos testifies on this behalf. If you would like a copy of my 
Duplex Scale Field Manual Guide , which lists the scales of the most popular 
pianos in the world that have Duplex Scales it is available for $20.00 The 
guarantee is, if you return the book, I'll return you your $20.00
