Hello,
Here are the external differences between prewar or wartime Contaxes and the Jena Contaxes.
If it can help some colleagues to identify better their 1947-49 Kiev, specially about their origins: does mine come from Dresden parts or from Jena?...
On the cover of Jena Contaxes:
1- View counter: "3" with round top, flat on prewar or wartime Contaxes. Idem for the distance scale (front part).
2- Rewind knob: arrow without central extension.
3- Rewind knob: central screw: 6mm (5mm on other ones)
4- Accessory shoe: square shape.
5- Accessory shoe: logo "Carl Zeiss Jena".
6- Rangefinder: grey/grey rather than green/yellow.
On the front:
7- Selftimer: black painted rim under selftimer.
8- Contax engraving different. Clearly visible: distances between C/o and n/x are more important.
Rear part:
9- No logo.
Back part:
10- Accessory shoe: number of circles more important.
11- Accessory shoe: tripod with moulded lines on the two parts,
12- Release button: with concentric circles.
It is interesting to add that Jena Contaxes may have slightly different front engravings, concerning the exact shape of the O, for example (less or more flat). And the rear/back part is heavier on some rare Jena Contaxes (c.175g instead c.115g). Last: a flash sync on the cover (last batch only).
Very probably, there are other differences I missed! Please, don't hesitate to add your remarks.
For the differences between early Kievs, don't miss the very interesting article on Luiz's site ! (Written by Claudio Asquini).
