Thats a Vuida e Hijos de Francisco Arizaga (Widow and Sons of Francisco Arizaga). The gun is a two barrel set, with original traveling case, for which I paid 1500 Euro.
Kyrie, the late Jack O'Connor gave Arizaga some pretty good publicity in his "Shotgun Book"--although he also indicated problems one might encounter with Spanish guns in general of that era (a couple decades prior to Diarm).
Re the photo in the post above . . . always good to exercise caution when laying your shotgun on dead birds. Blood is bad for metal. Don't ask me how I know that.
