I would just find it odd that Accardo is hanging out with Taylor Street guys (like Pranno) in the 1950's. Could be wrong.
Totally agree. But a case might be made that it's predominantly Taylor:
1. Accardo (easy) 2. Torello (not Amato as we've presumed) 3. Ricca (not Cerone; I think Cerone's hair was darker at that time) 4. Pranno (as noted before, just to the right of JB, sitting on the table) 5. Roselli (not Nuccio; he was their Hollywood guy at the time, no? Perhaps he was in town for the occasion?) 6. Buccieri (not the guy you think is Fischetti; I'm grasping at straws here perhaps -- is Chuckie English a possibility?) 7. LaPietra (in the white hat) 8. Nappi (immediate foreground with shades and cigar; it would make sense and he does have a Fosco chin).
