Majorjoel,
Good morning to you as well. Yes the family is from Bargi, Italy, a small town near Bolgna. Several famous guns exist from this family. One is is the Met, a pair of others are in the Musee de l'Armee in paris. Searching online I have found a few other examples as well. I have found a reference to the makers mark used by the family in "One Hundred Great Guns" by Merill Lindsay. It's not exactly clear which members of the family used this mark, however. I have a gun with this mark and would of course like to find a much material I can. I know there are are some other more definitive references on makers marks so perhaps they may help.
Thanks,
Jim
