Uhm, George, did you actually read what I wrote?  You quoted me immediately 
above your response.

I repeat it here:

<< This would involve either scrapping the rangefinder completely or 
**replacing the RF cam.**  >>

(Emphasis added.)

Four sentences later you say: 

<<...But you need to change
the focusing cam/gears/whatever so that the lenses are focused at
the film plane...>>


I certainly understand the purpose and operation of the co-incident image 
rangefinder. As I understand the Realist, as you turn the focus wheel, you 
are not only moving the rangefinder's optical components, you are moving the 
film plane to ensure correct/critical focus.  Am I mistaken here?  Is the 
Realist rangefinder not coupled to the film plane?

My point is/was: should a person desire to replace the vintage lenses with 
modern ones of a different focal length, you must either disregard the 
rangefinder, recalibrate it, or even remove it.
Alternately, you could convert the camera to scale focussing (like a Kodak 
Stero) by manually recalculating and relabeling the distance scale.
