For what it's worth, Fosco mentioned to me in an email that Gags definitely wasn't in the pic, and intimated that the only way DeStefano would have been in the pic were Ricca to be in it as well. Hence, Cerone/Mooney would be Ricca.

EDIT: Not that any of this matters, as Fosco's probably too busy defending Bill Cosby (yeah, he seems to have lost the plot a bit) to respond anyway.
