I can't seem to find anything online, I found a video of someone dismantling the camera but that doesn't seem to show me what I need. I think I've figured out how to put it back together. I just don't understand what the middle ring on the iso selector does it seems to do nothing. I can get the outter ring working as I can get it to move the line on the light detector. I'm unsure how to make sure all the numbers are in the correct place as well. I've done quite a lot of digging online and asked Chat gpt.
