fallboard vs. keytops

 Hi David,

Today I hope to find out what the key height spec IS for this instrument (and what elevation the fallboard guide pins should be above the keybed).? Not Japanese.? Will check keys vis a vis keyslip, fallboard gap when closed.? Shanks are just above rest cushions.

Thanks,

Alan Eder

Key height to spec at the extremes?   Keys look correct to keyslip?   i.e. key 
front looks like a square...key pins up into the key mortice a bit when key at 
rest?   Is this a Japanese piano?   if so not likely a manufacturing 
error...really does sound like a bedding problem.   A quick look at the glides 
would show if they were turned down abnormally...Does the fallboard have a 
normal gap at the top when closed?   How do the cheekblocks align with 
fallboard?   Keys much higher than the cheekblocks?   Check blow 
distance...shanks just above the rest felt...normalcy...
