... Guido is quite pesimistic about total number of Fed-Zorki cameras released...

All my Zorki data about Zorki cameras on my office PC unfortunately, but I try to say some facts from my memory if you don't mind ... An earliest so far known Fed-Zorki has s/n #00121 (Fed-Zorki manual guide), up to #00750 almost all cameras are covered in thin Zeiss leather, instead of late vulcanite. So we have at least 5650 cameras, of which only 900 units have "1949" markings. An earliest so far known type-b camera is owned by our friend Bill (sorry, I can't remember the exact number indeed ...)

Best Regards,
