This is a Schneider-Kreuznach Symmar-S 5.6/210 Multicoating Copal Lens - Made in Germany. The lens has been used and has some black paint missing. There is no fungus on the lens, the front lens has a purple tint and it looks like there is a very small spot in the shape of a 7 where that coating has come off (see photo #9). The shutter works on all settings, I haven’t timed them but it does work. This lens is sold “as is” since it has been used.
