Ole, mine is the Rollfilmkamera model, the direct precedent to the Inos I. It's 6x9 only (Inos was 6x9/6x4.5 with double framing windows) and has simpler accents etc., but otherwise very similar; it has a 10.5 cm f/4.5 Skopar in rim-set Compur with unit focusing, pull-out front standard rather than the self-erecting type that started to show up in the late 1930s, and no body release -- but the waist level finder is clear, clean, and bright, so I can cradle the camera and release with a thumb, and hand hold dead steady about 90% of the time down to 1/25, and effectively 100% at 1/200. This was surely a very expensive camera in 1928. I've been tweaking and tuning it since I got it.
What'd I give for it? I traded a lens and shutter. I got the combination of 105 mm Dominar Anastigmat and Press Prontor for $10, with the shutter jammed solid in the open position (based on how it was mounted, I think it had been used for enlarging), repaired and cleaned the shutter, and machined the mount into a retaining ring, then fabricated a lens board to fit a Baby Graphic. Since I have more time than money just now, it was a pretty good deal...
I'd love to have a Bessa rangefinder, or the 6x9 Prominent (with Heliar, please), but until I find my gold mine, this Rollfilmkamera will do the job nicely...
