Anyone know who this bust is of?

On the left below; I would guess a Sforza due to the solar rays off the neck and human headed dragons on the cuirass, but it would be more likely to have bangs.

The attribution is wrong on this Warburg-related page:
Workshop of Verrocchio, Bust of Lorenzo de' Medici, clay, 1466 circa, Boston, Museum of Fine Arts [38.11]; Stefano Ricci, Bust of Lorenzo de' Medici, earthenware, ante 1825, Oxford, Ashmolean Museum, Fortnum Collection [38.12].
