Bodybuilders like Coleman, A Baker, Pearson, Wheeler, D Jackson , Ferrig... etc... all appeared to have some type of Calf Assist™ which most of them seemed to have removed later on or they 'dissipated' on their own, depending on what was in their calves. Coleman, Wheeler(see last contest), and Jackson ended up with the inner Calf Melt©, whereas Pearson seemed to go back to his original calves, small, but inner calves intact, possibly due to 'mere' implants and not muscle-deforming oils.
Roland Cziurlock had good calves but later on lost the 'good calf genetics' look in favor of larger, calf-diminishing inner knees, possibly the lower sartorius picking up the slack for inner calves due to postural issues. Cziurlock did not, however, suffer from inner Calf Melt©.
JP F*x lost his full calf look and ended up with more awkward calves after his squat mishap.
Gunter Schlierkamp seems to now have inner Calf Melt©, although he always had an awkward knee/calf posture, reminiscent of C. Schwarzenegger, sans adipose tissue and non-tapering ankles:
