Hey Jim
  Did the attached pictures help answer any questions. By the way both Bs have the New Weickert felt hammers.  David brought up a good point about voicing.
 IMO This pianos can be voiced a variety of ways. But the two pianos mentioned although they are both Bs but built differently...I truly wonder if they could be voiced to be identical or even similar.  Any way Davids soundboard resonance reduction  thought is apparent in both pianos.  Yes still much to learn, explore and have fun on the journey.
  The big thrill is to hear music coming out of a new re-whatevered box. Do I hear a cheer?



            
    
          
            
               It's dark, powerful and                    voluminous 
          
        
    are you by chance a wine taster by trade <G>  no
     my tonal envelope is power with out noise. Or as Starr Taylor says" Without the strident clang that permeates the piano tonal landscape of today"  Predominant fundamental balanced by upper partial clarity but no clang and little percussion on hammer impact sound.  I seem to be allergic to it
can I take this to mean prominent fundamental and lower partials    with a reduced prominence of the uppers?
    
    
          
            
The design spec: is a grain angle that                    follows the long bridge (approx 30 degrees off the                    long side)
          
        
    
    hmm.  Yes for me I've always measured it off the spine. Easier. Stwy models S,M,L,O are 45 degrees,(some )s in the 30's) and A's thru Ds are 40 degrees with some anomalies
    
            
          
,serious                  curved cut-off bar,
                  
                
        
      where does the cutoff end in relation to the tenor    ribs? See pictures
