I've thought that #6 resembled Centracchio, but then I thought the same thing as you, namely: why would he be in that photo with the bosses?

However, we don't know who or what's outside the frame of that photo, and #6 is definitely a younger guy - around 30 isn't far-fetched. AC was born in 1929, IIRC.

FWIW, Centracchio's eyes are a close match to #6. I think it's a possibility.

Snakes, can you think of another guy circa 30 years of age who's more likely to be 6?

And if that's AC, could #4 be Infelise or Ferriola? (This is a total winger here, but #4's been driving me mad...) I've had no luck finding younger photos of either.

EDIT: I always understood that Destefano was never made, which would make unlikely that brother Mario was.
