Hi Ulrich,
There is something I don't really understand in the chronology about the Jena Contax.
From your articles (the Conkies), I understand that:
1- the production lines are first made and tested,
2- the first 1947 Jena Contax and Kiev Contax are made,
3- the three production lines are dismounted and sent to Kiev.
OK. But with what were the following Jena Contaxes made? From spare parts, originally made in 1946-47 and used when necessary to mount the other series?
What was the exact date of the sending to Kiev?
Sorry: my German is non-existent...

Merci. Jacques.
