How long do we have to beat this horse.

Fosco's wrong. A book transposed the pictures of Pranno and Potenza. The mistake has been repeated all over the internet.
If there is any doubt, here's a picture of Pranno in his 20's. (lower right)
Pranno et al

#3 isn't Pranno, it is either Parrot Nose Potenza, or Queenie Simonelli.

Simonelli obit

Fosco either doesn't know who they are, or he can't get the hundred bucks together.
