Kodak's folders like this No.1 Pocket Kodak used 120 rollfilm prior to the 1932 introduction of the 620 format.
Kodak marketed the Kodar lens as a mid-level product, situated between the older standard Rapid Rectilinear and the later three-element Anastigmat design. The Kodar does a very credible job of making images, though I would be hard-pressed to distinguish them from those from the Rapid Rectilinear. What really appeals to me about this camera, however, is the fact that the aperture can be stopped down to f45. That means 400-speed film can be used at the top 1/50 shutter speed in direct sunlight, and in low light one can still use small apertures with good depth of focus.
I usually make some minor modifications to my old Kodak folders to make their use more practical. A flap of black tape covers the ruby window except when I am advancing the film. A lensless eye-level finder taken from another old camera is held in place with duct tape, and it makes composition considerably easier than using the squinty little reflex finders. A depth-of-field table for the particular lens shows the hyperfocal distance and assists in establishing the range of sharp focus at different f-stops.
I tend to employ cable releases with my old folders at it is easy to jiggle the camera using the lever release out near the lens. A lens hood would also be a good idea with the uncoated lens, but it still produces nice contrast and sharpness as long as you don't angle it too close to the sun. As may be seen in the last photo, I haven't yet stamped out all the light leaks.
