notching in 3rd section

[Jim Coleman, Sr.]

To JimRPT:

The Baldwin SD6 and some previous versions had the slanted bridge 
notching. This was a copy of what Steinway had done for a number of years 
previously. My thinking is that this was done to make it impossible to 
tune perfectly clear unisons in order to give the impression of better 
duration in the 5th and 6th octaves. Later Steinways and Baldwin SD10s 
have gone back to maintaining equal lengths of the three strings of a 
unison for the purposes of getting cleaner unisons.
