They're all different shapes and (within limits) different sizes, Nemmie.
The photo of mine above was taken from a slightly "above" angle, so the pulls look almost
like shoulders themselves.
The ones I describe as having shoulders are the bigger, later ones (you're perfectly correct) - like this one, where the shoulders are practically horizontal, under a wide flanged rim. Again, the photo is from a "slightly above" angle.
The positioning of the pulls can make a huge difference to the overall appearance!
