Found a bunch of vintage camera items at junk sale today. Can't identify what this silver leitz equipment is for. It has optics inside. It also has a spring loaded button that could possibly notch the edge of a film. Anyone know what it is called or used for?
It doesn't have any markings as to model number. It would seem to attach to some other piece of equipment as shown by the slots on the top and bottom. There was a card with "Focomat" written on it in the bottom of the box, but that seems to refer to another part in the box. Also, it doesn't attach to the zoomf or doorx.
