Hi Joe,
              They are Renner (Hornbeam). If it's a later SF10 with Renner 
hammers, that's where the weight has been added.   The factory changed the 
hammers, but not the CNC weight off pattern.
Not so unusual to find the wippen rail mislocated. Magic line and dip will 
trouble shoot the problem.  I think the dip specs is .400" dip, giving 
about .020" of after touch.
Just a couple of thoughts to try.
Regards Roger
