Moving Damper Guide Rails

[Tony Caught]

Hi Terry,

Tis well known that Beijing pianos only sound good around Beijing and than
Shanghai Pianos only sound good around Shanghai. (good being relative to
Chinese pianos only)  From what I've seen it is a mixture of both
compression and rib crowning but  the factories are air conditioned by open
or closed windows so naturally the pianos made in Beijing would have drier
soundboards than those from Shanghai. (once again depending on how dry the
timber was to start with)

Regards

Tony
