not want it to be hitting internally in the rangefinder mech. Most M3s 
are easily adjusted to 0.7m. A few, however, will stop internally 
before you get to 0.7m. That is the best you can do with those cameras 
and be sure to tweak the tab back a bit so it it the stop doing its 


Personally I would get a good Leica tech to do the work. It is easy for 
them to double check the rangefinder's accuracy at the same time.
