SS Dolly rangefinder.

Hi all,
I got inside the rangefinder of this camera, mirrors are not good, I already asked replacement to Martin Seelig, in about 3 weeks I will get them hopefully.
Some photos explaining how to get inside the rangefinder how it works.
Fixed mirror.
Rangefinder how-to.
This rangefinder works only with 2 mirrors, one is higher (left) and the other is shorter so when looking through the rangefinder the image is split in two halves, upper is the real image, lower is the images coming from the mirrors, matching both images and the focusing is done.
About how it works, the blue line is connected to the helicoid where you focus, the right mirror moves according to this as well.
For adjusting the rangefinder... still learning from it but I think the yellow arrow does vertical alignment and the red horizontal alignment, I can be wrong coz barely I can see anything with such mirrors, when the replacements come I will go further.
Thank you for watching,
Alex
