The UK's Guardian newspaper published a photograph of the late minimalist-artist Robert Morris by Grant Delin. The portrait-orientated photograph shows distinctive rectangular-shaped notches at the "top" of each edge of the negative's "vertical" boarders. Can anyone say which camera made this image? All I can discern is that the format is 645.
I don't think you can determine what specific camera left the observed notches, because it's not a feature or property of the camera's construction. Rather, it's a part of the construction of the film holder.
The image you link to is a print of an uncut negative. The notches are simply the part of the film that is left visible by the rails of the film holder.
