The mount and barrel differ significantly from the Nikon mount 1.1. Both take the same hood and front cap. It came in it's own special case, with the only 50 mm brightline finder Nikon ever made. As rare as the Leica mount 1.1 is, the viewfinder is MUCH rarer. Apparently most were lost over the years.
Regular finders show ONLY their field of view, without the frameline.
