Open back scale lengths are not what I'm describing, although that is there 
also. It is a much lower pitch, exactly like the sound of knocking on the 
plate behind the hitches.

I wouldn't describe it as resonance, in the sense of a sympathetic 
vibration.  It's just like you whack the plate with your knuckles when the 
hammer hits the string. It doesn't continue to ring.

No, I have not redesigned a Baldwin to see if the sound goes away. I don't 
own any that I can experiment on.   Now that I am no longer at the 
university, my exposure to Baldwins is reduced to rare to never.  The SD-10 
at our church is the only one I have access to and I'm not going to go up 
there and tear it down to experiment with changing plate height and 
downbearing. Muting the backlengths might be one way to reduce it, but that 
is like taking allergy medicine to deal with an allergy -- you're masking 
symptoms and not getting to the problem.
