Beautiful Ernst Leitz Wetzlar Summitar 5cm f2 lens with a serial 578927, see photos for details. The lens has a defect on the bottom right side part of the front glass element, I tried to catch it with my camera but it is hard to show. I am not sure if it is oil residue or anything else, it does not look like "classic" lens fungus, this is the reason I auction it as not tested and "sold as is". —————————
