Can't tell for sure until sampled, but an authority on this type of equipment (someone who owned more than her fair share, all natural) once told me that one indication is whether the tops are curved or are flattish. Natural shapes are flattish on top since the weight hangs, but the other kind is roundish on top. The ones in the picture are roundish on top so I'm guessing there's been some help here. My two cents worth.
