Thank you all for your tips and support.
I will put different pictures than others with some useful if one day you get this camera in your hands.
I started with the shutter, it was pretty soft and after finishing it, still soft. I guess 200 is 80-90, my shutter speed device is KIA.
Pronto shutter cock leveller.
Then the rangefinder was a bit off vertically, open the top cover is no mistery and inside everything is pristine.
Vertical offset of the rangefinder.
These two small screws at the edges control the vertical offset of the rangefinder, loose one, tight the other and vice verse until you see both images at the same level.
Thanks for watching.
