Description Wrought iron and embossed sheet metal strongbox chest. The sheet metal was made from solid by hot forging and carved with a chisel according to the development of the predetermined design. The keyhole is located in the center of the lid and is hidden by a retractable escutcheon (technical secret). The one located in the center on the front is false (psychological secret). The lock occupies the entire internal surface of the lid and is of the multiple bolt type. By means of the thrust impressed by the rotation of the key, a complex mechanism of levers moves synchronously and simultaneously all the thrust springs of the snap bolts placed in a fan shape on the four perimeter sides of the lock. This particular multiple bolt locking device was devised in Germany (Bavaria) in the mid-16th century and subsequently spread throughout Europe. The strongbox in question is equipped inside, in the lower left, with a small compartment, protected by a lid also equipped with a push-bolt lock which was usually used to store metal coins and precious objects.
