Yes you are right!
i first was not sure if this was a moving binder, but after looking to the video of Uwe i understood this is also a moving binder (but connected in an other way than the binderset i first looked at.
All in all, I do need quite a few parts for this solution (the other option was a complete set)
and I don't think I'm doing enough binding to justify the effort of conversion and total cost .
i think i will start trying with a non moving binder (for most binding my adler 69 and 67 with moving binder setup will do anyway)
