Say Ed -
Forget the still pictures of the bridge, if that's a problem for you.  I'd 
much rather watch the video of you leveling the Lowell gauge to the top of 
that thar bridge.  One of those "direct to video" releases, I 
suppose.  Fact is, I can't visualize how the gauge would tell you much of 
anything with that configuration.  Unless I'm mistaken (or 
mis-visualizing), there's no direct relationship between the front string 
termination (the agraffe) and the distal side of the bridge.   Actually, I 
wasn't sure, from your description, what, if any, bridge-segment 
measurement you did take.

Question for Ron N -
What is the "side bearing angle at the bridge pins"?
