Lens faults generally won't cause sharply defined defects on the film. When the camera body causes problems it's most often long scratches from some sort of damage around the film gate or on the pressure plate. The other common problem area would be light leaks either because of deteriorated seals on the back, or faults with the shutter.
The specs and spots on your shots are not typical for either camera body or lens problems. But as stated, they are usually indications of poor dust control during processing.
