Where IS an authoritative source for historical pitch levels? I also was 
wondering about pitch on a couple of older pianos, specifically, an 1865 
Steinway 7'4" and a Viennese grand from before 1900 which I might be asked to 
rescale. I remember reading that Steinway used a VERY high pitch sometime in 
the 19th C., which might help explain some of the old scales, but I don't 
remember where I was reading it, and would like to have some confirmation. 

Thanks,
