Hello. First time posting on the forum. I purchased a used side by side shotgun from Simpson LTD. They advertised it as an AYA. The shotgun barrels indicate the gun was mad in Italy and it has Italian Proofmarks. There is no indication which manufacture made the shotgun but there is a stamp that is not a Proofmark. It is a shield with a star in the shield. Does anyone have resources in regards to the manufacture stamps? I have emailed the proofhouse in Italy that proofed the gun but they have not responded. Thanks
