Seth, here is a list of Italian gunmakers where I could find four Belleris: Luigi, Antonio, Livio and Angelo. Italian Database . At the bottom of the list there is an email link for Edoardo Mori, in charge of the website, who can surely help you. Sending him pictures will surely help.

(There is also Giuseppe Belleri (born 1934) engraver mentioned in a book by Mario Abbiatico.)
