Most of the cameras that were sold in the 80s had some kind of automatic exposure control and electronic shutters. That's cheating. Start with a completely mechanical camera and a 50 mm lens, nothing more is necessary.
I would look at the Canon FTb series or Nikon FM series, or a Pentax K1000.
so substitute the world manual in :fawk:
