Don't know if that's your version or not.
No, I believe it's the older Sironar N. However, unless it is
misassembled or the view camera components are out of spec, I doubt that
on the same film at the same magnification using a reasonably small
aperture you could tell the difference between the Rodenstock and the
Zeiss. They both are probably diffraction limited by f/11 anyway. Of
course the assumption is a stable tripod and no wind.
