If number 10 isn't Sam than it's definitely not Blasi.

Amato, Accardo, and Nicky Palermo are the only ones that are pretty much confirmed based on what we know these guys looked like. The rest are going to be either (a) guys we have never heard of or (b) guys of which we have no (or limited) existing photographs.

My pick for the younger guy is Nappi. Why not? He was in his late thirties at the time of the photo but was already well-connected. Plus, Fosco said he got the photo from a relative of his. He also slightly resembles the only photo of Nappi that I have ever seen.
