Find a local Camera Club, there is a good one in Chicago but I stopped being a member a few years ago

There are still people alive who used these camers and shoud be able to help you. I't really just a matter of understanding the era and 'fingering' out the camera, some of your problems may be from the camera not working. I'm near Chicago, PM if in the area.-Dick
