As the owner of this shotgun I am 100% sure that the making of the gun was in Italy. This gun was passed on to me from my employer and friend of thirty years as a gift for dedicated service to him during those years. He was a imigrant Italian and avid sportsman who returned to the old country on a regular basis and in the early years always returned with a new firearm.
Regarding the question of whether the gun is a true sidelock or a boxlock with sideplates the following may clear up question. The smooth round type button shown in the picture on the left side goes indent or exdent depending on whether mechanism is cocked or not cocked.
