Those older, better styles used to be made by Renzo Tattini
No clue who's SF's source now, but I doubt they haven't switched if the current trendy look is any giveaway.

Couple of things:
1. Berluti is a French company, not Italian.
2. Gravati and Moreschi make mainly Blake-welted shoes in unusual leathers. So if peccary, ostrich etc. are your thing, they are the companies to go to. I have a pair of Moreschi cap-toes and they are very elegant and light as a feather. However, the general opinon appears to be that Gravati are slightly better.
3. A. Testoni also make very sleek Blake-welted shoes. In North America, you often used to find them 'made for' high-end department stores or men's shops (you probably still can).
