Yeah. I found a bunch of different clues from FBI reports on MaryFerrell that convinced me (at least) that Carmine Lombardozzi cooperated for a time in the late 1960s. The best clue was a 1968 report from a Gambino member who said he was at Apalachin and spent time in Baltimore on Family business. Lombardozzi was the best fit.

I wrote it up here.
