This was my father's still camera, responsible for so many family photos in the 70s and 80s. I think he finally upgraded and stored this one, then I was gifted it and just put in a box. It's dusty and could use a cleaning. I do not know the ins and outs of the camera but was able to open up the back (see photos). More than happy to try and answer any questions. My dad is 84 now and might be able to remember things about it but won't know til I inquire.
