Overview:
This version of the Astro-Kino IV is rare, usually these are the color-film version called Astro-Kino-Color IV. So this lens is older than these other ones. I haven't seen many of these around. Beautiful 1950s West-German 16mm projection lens.
Condition:
Lens has some optical damage, some scratches and some heat damaged glue on the rim around the back group. No fungus or haze. See images. I used a strong LED backlight to highlight the damages.
