I believe its the same model (though not the same camera) that I owned for over 5 years. That was a model II. This example is in better condition than mine was. I was also was lucky enough to get a Schneider Curtagon 60mm and Tele Xenar 150mm. That combined with multi coated Zeiss lenses made it an excellent outfit. It was, indeed, more reliable and easier to load correctly than the Pentacon six.
