Todd,
I have never seen what you described and have had a few rolleis with out of
alignment plates. All needed to be repaired.
I have spoken with Harry on this one and unless he is wrong as well, this is
one thing that is more than sloppy application of the plate. It means the
rails are sticky or the plate is out of whack.
Sometimes an impact will leave NO DENT!!! Drop the camera a rug and on a
front corner. No dent and the plate then becomes out aligning which then
means the lenses may be out of alignemtn as well.

But that is my point. You cannot tell. If the front plate is uneven it
might not be due to impact, but just a sloppily applied front plate. So
the camera may be perfect, other than the misaligned front plate which
is easy to fix.
Now if there is obvious impact, then you don't have to look at the front
plate alignment, just look at the big dent.
