Can  anyone explain what a "pin  registered M3" means.  It has to do with a  
Leitz Reprovit II  Copystand.

Thanks,

I might add, that for projection, you need special mounts that hold the  
frames in a precision manner.  Gepe makes these mounts, maybe others do  too.

Pin registratrion is a way to hold each frame in a precise  place  relative 
to 
the frame line, so that you can go through and  expose a roll of  film, and 
then rewind, and double expose, triple  expose, (whatever), to add  other 
information to the frame.   
---
It also enables you to make a series of shots that are identical in  frame,  
so that for example, you can do slide animations with  multiple projectors.   
I 
hope that is clear.  I would  suspect a pin-regfistered M3 would be a rare  
thing.  They are  most common on high end motion picture cameras.  I've  used 
a  
pin-registered Nikon for copystand work primarily for multi  projector  slide 
shows.

Hope this  helps.
