Askania Z - vintage 35mm movie camera
The camera is in very good condition. It seems that it wasn't extensively used. So, it is great sample both for a museum and for an user.
Looks like Askania Z from 1930's to me, though I'm not sure. Serial number is 3013069.
The camera is held by my friend in other city, so if you have any questions, please ask. I'll answer them as soon as I get reply from him.
