I found the old cameras of my parents in the garage. Both are the same. My dad said he got his camera on the occasion of the First Holy Communion. It was a long time ago. The second belongs to my mom.
I have no idea if they are still working. If they are, I wouldn't like to spoil them, so I'm not currently changing the parameters at the moment. I have to find out how they work because I have never used such cameras.
