"Like Carmine Fatico, Ruggiano was given a crew to run probably in the early 1970s"

It looks like I was wrong about Ruggiano. He never was an official captain but may have been acting for Fatico in the 1970s. He is often mentioned as an official skipper, particularly in the 1980s, but him being a captain actually doesn´t seems to be the case.

So, Dellacroce´s crew was split only two ways (between Caiazza and Fatico) and not as I previously said in the OP between Caiazza, Fatico and Ruggiano. Sorry about that.
