NSN. Made circa 1645. 52 caliber with 12 ½” over / Under barrels on each gun. These barrels revolve so it allows you two shots per each gun. These beautiful pistols are the work of early master gun maker Giovan Battista Francino. His surviving work is of the finest quality and worthy of world class private or institutional collections. The Brescian region is well known for their pierced and sculpted metalwork which this pair clearly exhibits. The condition is excellent! This pair is truly world class!! (DALLAS LOCATION)
