Dear AlexanderK,
you mean that your Kiev is fake? It is interesting to hear your arguments why this is 1952 Kiev. I do not think that it's fake.
I think that indeed no one was able to produce Kiev III before 1952 in Kyiv. The guy from Dresden who was involved in light-meter production was left after Zeiss factory dismantle in Jena. According to Werner Widders recollections, people from Jena were able to assemble light-meters only starting from 1948. From this fact it follows that:
1. Very few Contaxes III were assembled in Jena prior 1948 (probably as prototypes)
2. Some Contaxes III were produced starting from 1948 (just my guess)
3. Some "Kievs III" were produced starting from 1948 until 1952 in Jena (could be, that due to the order of SMAD, Kievs III were assembled instead of Contax III. Again my guess)
4. Some Kievs III and Contaxes III were assembled for German black market.
5. Official production of Kiev III was started in 1952 in Kiev.
I have very simple explanation why Kiev III appeared before the official production with the light-meters from 1952. (I suspect that that was your, Alexander, doubt about the originality of your 1948 Kiev. Correct me if i'm wrong). In Dresden period everyone was able upgrade Contax II to Contax III by sending the camera on the factory and paying some money. Very probable that the same practice was adopted in Jena or Kiev. Somebody who possessed 1948 Kiev II wished to upgrade it to Kiev III in 1952 so he went to Arsenal and made the upgrade. To mark properly this modification the cold shoe got the letter A as the standard Kiev III from 1952.
I have the next set of questions:
1. Kievs 1947 have 5 digit serial number; Kievs 1948-1951 have 6 digit numbers. That's fine. Suddenly Kievs III of 1952 got again 5 digit serial number. Why? People did not expect to produce more than 999 cameras?
2.With growing number of Kiev III in 1952 the serial number became 6 digit. The reason to do this is clear. My data shows that with the switch from 5-digit number to 6-digit number in front of the serial number appears "A". What happened?
3. The serial number engraving was quite uniform during 1950-1951. Suddenly the deviations in fonts appear in 1952 as well as the changes in the way how it was engraved and in the filling with paint (many of serial numbers do not contain this filling at all) New engraving machines on the factory? New personel? Another place of production (not the Arsenal factory)?
