A purely speculative question: where do we think Sollozzo has been all these years? Hagen's rundown on him is pretty sparse, so it seems there's not a lot of Sollozzo stories floating around mob circles. Vito knows he ran some prostitution before the war, but Tom doesn't know Vito would know that, so Tom's own research trail seems to peter out at some point. We know his business is anchored in Turkey, France, and Sicily, and he has a family in Turkey, so perhaps he was stuck across the Atlantic for the duration of the war? On the other hand, he also has an American family, and very matter-of-factly knows who has the best veal in New York City, so he doesn't seem an out-of-towner. He's also done some jail time.

So: whence Virgil Sollozzo?
