Great old camera - This camera was made by the Zeiss Ikon company in Germany. They were one of the premium camera companies of their time. It is a Contraflex model and has a Synchro Compur lense, 1:28 50mmCarl Zeiss. It worked well the last time it was used, which was some time ago. It advances and the lense opens when the button is depressed. It has a flash window that opens when the release is pressed. The case is included but the weather is becoming old and the strap separated on both sides. It attaches to the camera with a screw on the bottom, where a tripod might be attached.
