Pittsburgh's heyday was after 1937 when Frank Amato Sr took over. By 1946, state police and local law enforcement had Pittsburgh between 45-55. Pittsburgh has always operated very similar to a Camorra where they assigned bosses to each area. High ranking associates were held in very high regard and some of them were actually better earners than some made guys. By 1950, Pittsburgh had these guys assigned to their respected territories:

Frank Amato- Braddock, East McKeesport
John LaRocca- Pittsburgh (city limits)
Kelly & Sam Mannarino- New Kensington
Tony Ripepi- Fayette & Washington Counties
Mike Genovese- East Liberty, Bloomfield Ave
Joe Regino- Altoona/Johnstown
Joe Pecora- Penn Hills-then moved to Chester, WV along Rte 30
Charlie Imburgia- Warren, OH (Trumbull County)
Paul Romeo- Youngstown, OH
Vincenzo Tripodi- Steubenville,OH (Cosmo Quattrone was his #2)
Jack DeSarro- East Liverpool, OH
Louis Volpe- Turtle Creek
Salvatore Marino- Sharon, Hermitage & Farrell, Pennsylvania
John Scardina- Lawrence County, PA

Each one of these guys had their own crews of made members and the members had about 10 associates each. Each one of these guys made sole decisions in their territory without the brass sticking their beaks in.
