Vintage Vivitar 400 SL camera

I purchased a small estate and a handful of vintage cameras were in there. I have no information on the camera, I do not know how to use it. If you would like more photos please message and ask! What you see is what I will be sending, so just the camera and a battery (dead). Be sure to check the photos to see what lens you are getting. It will need to be detailed. If you know how to open it and want to see photos of the inside, message me how to open it please ;) Item will be package with safety! Please reach out with questions. Crosslisted BF3
