Or thinking about this you could ask if anyone knows how this should be done
on "rangefinderforum" I think it's www.rangefinderforum.com , try Googling
"rangefinderforum".

Hi Rob,
Thanks for the tips. Very helpful. The URL you gave for the RF forum is spot
on.

The graflex.org site has instructions on how to calibrate a
couple of different rangefinders that might help in a
non-camera specific sort of way as well.

What are you trying to calibrate to what? External rangefinders have
distance scales on them as do your cameras. What needs calibration? Are
the rangefinders inaccurate or is the camera focus scale inaccurate? Or
do you need to make index marks on the rangefinders to correspond to the
camera's focus scale? Or did you buy non-photo rangefinders for boating,
golf, artilliary, etc. calibrated in yards rather then feet?

Bob,
Let me be more specific to answer your questions.

I want to know how to adjust these 2 "external" rangefinders which seem to
be out of calibration. I believe my cameras are in spec as far as focus is
concerned. The images are not coincident laterally and when I focus with
them on an image at a known (measured) distance to make the images
coincident the readout from the rangefinder scale is not correct.
So I need to know what I need to turn to make the adjustments and what
order of adjustments to make.
And yes these are rangefinders designed for camera use and not boating etc.
No idea if Voigtlander ever made devices for such use.

Thanks

Hi Dave,

Somewhere in the back you'll see a little knob or screw like thing with
a slot in it. The slot is for a thin flat head screwdriver to turn the
screw and calibrate the RF. Focus on your measured distances and turn
the screw until it is in focus; try at 10 feet/3meters, 50 feet/20
meters and then infinity.

Cheers,
Bogdan
