Ah! What internal number does the above one have? I can't find it yet. Would it be in the same sequence as the others? I can look through all my other brochure/manual/newsletter collection, but I haven't found 4 / 24 / 29 / 31-34 yet. I'll keep looking.
Do you remember Zeiss Camera Lens News 1997 - on? I have some PDF's of the early ones.
