Hi, first time poster please be gentle. I recently found my Grandfathers old Super 8 camera. Kobena 421. It seems to be in pretty good condition and runs with batteries. I was curious about the manual aperture controls. They don't seem to switch when I turn the knob. It just stays on 22. Does this mean it's broken or does it need the battery and/or film in the camera to get this to move?
Any help would be much appreciated. I'd love to get this thing working and get a couple rolls of film to mess around with.
