Hi i just bought a Konica pop-super. When i got home i noticed that the film pressure plate are missing some kind of spring. Is it still possible to use the camera or should i make something that will work as a spring? (I was removing the pressure plate in the photo to know how it would look underneath.) As you can see on the black camera there is some kind of spring with some film guide, do i need that? ( The black camera isn't mine )
