I have a 1954 Groma modell N which works very well in every way except one: The link between the margin release mechanism and the margin release button is missing. I am planning to replace the old, missing link with a piece of metal wire. I would appreciate if someone with the same typewriter model could post a photo of the mechanism, to help me understand where the wire goes in between all the other parts.
