Over on the Leica Camera User a Leica rep responded to this "ruler  
test" with some insight. Because the range finder windows are off  
axis from the lens the test is really quite useless for rangefinder  
cameras. One really has to check the focus with the film plane and  
the subject plane at absolute parallel - as that is the only time  
that the rangefinder  and subject will actually work. Makes perfect  
sense. When you consider this while testing; results become very  
different. It quite altered my way of testing and working with the M  
in the last few weeks.
