[CAUT] Original SD-10 Key Height

[Fred Sturm]

	I think Eric is right, this is certainly the most plausible  
explanation. The felt might not even have been replaced - might have  
been wrong in the factory (designs aren't always followed carefully,  
felt might be mis-marked, someone might have ordered the wrong felt,  
or taken the one for a different model by mistake). The tell tale clue  
is that you would have a lot of paper and cardboard punchings at the  
balance rail. Reduce them to a standard amount, then go with thinner  
back felt enough to get about 2 9/16" height, and you will probably be  
fine.
