Ok boys, I need help on this one. A buddy of mine bought this at a flea market in AZ. Single shot target pistol. Caliber is marked 7x45 , one side of the gun is marked "UNIQUE I.S" The other is marked made in france and (pardon my french) Manufacture D'Armes Des Pyrenees" with Nygord Percision Products- Van Nuys Ca. This is a break action singe shot thing with a trigger that goes off if you sneeze in its general direction. So does anyone know anything about this? Can you buy ammo for it? What's it worth?
