My FIL just gave me a Franchi Brescia O/U 12 ga. It has an Al alloy receiver. I can't locat a serial number on the reciever. I did find a number stamped on the barrel assembly back near the breach on the under side. Anybody familiar with these things? He has had since the 80s and it was used when he got it so it's been around for a little while.
