Very good lens.  1984 year of release.

The Nikon adapter is set. Only very little dust can be seen but it doesn’t affect the quality of the image as at the point of the dust the image is way out of focus. No haze, no fungus, no cealning marks or scratches, no separation of the glass elements and the metal barrel. The aperture blades are oil-free. Smooth aperture ring with distinct click stops. Smooth and nicely damped focus ring (100% Leica feeling). Serial number: 3338116.  No original front + rear cap Nikon.
