Hallo all,
good to read there are other users of that good 520/16 too. Could not believe I get such a perfect exemplar. A joy to use too. Thanks for reading my post.
I live in Seoul for some years, all my literature on Zeiss is at home in Austria. So I cannot find out the right year by the lens serial number. As this Tessar is uncoated, I assume an early one. All internet sources say the 520/16 was built from 1937 to 1939, when this is right, I assume 1937. But I do not know, when Zeiss started with coating. Any better ideas?
Regards,
Walter
