I would say the Pittsburgh 'business model' was interesting. They had about 3 capos but each very very powerful, there were no lightweights. Kelly Mannarino was an international power. And Ripepi was a strong Sicilian boss.

The Pittsburgh post gazette has old records of each one of the major crime events at the time. They were well aware of the name Frank Valenti even Pre Apalachin. He was a relatively high profile, smooth talking gangster.

This should go in old photos, but its a great article nonetheless.
