If by any chance you get a 70mm magazine, freeze a lot of BW rolls for future use and have or make a developing tank for the long rolls - what kind of enlarger would you use? Anyway - are these real 70x70 negatives or 6x6 on a 70mm roll (Regarding the image circle diameter of standard lenses, the tilt/shift lenses being an exception maybe)?
