Dann war meine Annahmen richtig. Then, my suspicions were right. Und danke für den Schlüssel der Seriennummern (ist ja genauso wie bei KMZ) And thanks for the keys of the serial numbers (as is indeed as KMZ) http://www.vfdkv-forum.de/viewtopic.php?f=26&t=5591
right, it's the same as KMZ. I wonder a bit why KMZ starts the numbering with the year as the 2 digits of the serial number on the Zorki 1 so late, the Zenit and Zenit C (and the Moskwa too) have this years before. And I wonder why FED never uses this scheme...
