The camera is untested. I did open the back up, please see photos

All the knobs turned and the back opened with no issues. I had to raise the rewind button and turn it to the right and it popped open. 

I did find a pdf of the manual on Orphans Cameras site for download. 

It has a Steinheil Munchen Cassar 1:28/45mm lense on it.

Minor scratches due to normal use and age. 

Please see all photos
