Mamiya Press & Super 23 - Rangefinder adjustment with comparison

Comparison of the rangefinder systems of Mamiya Press 6x9 and two different Mamiya Super 23 models (similar to Mamiya Universal Press).
You can see how to open the top cover and adjust the rangefinder on each Mamiya. Hope it's helpful.

Many thanks for the video. I've got a mamiya super 23 with 100 mm f3.5 sekor. When I focus at some very distant object and turn the lens focus ring I get infinity right - I need to turn all the way left and the infinity mark lines up exactly with the red mark. Regrettably, the closer objects do not focus properly. I've wasted a few films trying to get it right. When I focus across my room I get a camera viewfinder reading 5 m while a laser viewfinder shows 3.7 m. For an even closer object camera viewfinder shows 2.7 m while laser reads only 2 m. How to fix this, please?

Would this work for a 600se??
