Just reviewed this entire thread, and I'm going to base my final guess on something Joe E Brown contributed:

Quote:
Just seeing this photo for the first time. Not sure if this has been determined here but number 5 is Nicky Palermo and the event is probably the plumber's picnic that he hosted back in those days. I believe one of his daughters married an Accardo. He was also father-in-law to Frankie DeLegge Sr. Palermo ran a burglery crew out of Melrose Park. A very reliable source told me that at one point JB was talked out of whacking Palermo. Don't know what Nicky did to piss Tony off.


I think that the context of the photo is very important, and that it's more likely that not that not just high-ranking guys were present. Thus the argument that so-and-so wouldn't dream of being in the presence of so-and-so means a little less to me.

My final guess, dammit:

1. Amato
2. Accardo
3. Potenza
4. Glimco (doubtful, but a recent hunch)
5. Palermo
6. Centracchio
7. Gianola
8. Adduci
9. Ricca (based on something Fosco mentioned to me, and that I believe #10 is...)
10. Mad Sam

Now tear me apart!
