It is a feature that the film winding by Red Window is very simple way that causes the winding mechanism to be simple, accurate and it makes a camera itself compact.
Most Spring Cameras(Folding Cameras) have a red window, two or more sometime, for film winding. The medium format 120 film has a back paper and the exposure numbers are printed on the back. The film is winding untill next number comes on the window. The camera sometime has a green window instead of color red.
I love this simple way of film winding very much. They seldome have a problem of the film winding. Most cameras have a shutter to the window in order not to leak the light from outside. T.Kubo/X-PDS
