Hello guys, i have found a G. Gamba trap gun that was converted to a sporting gun at some point teague thin walls installed on it. It was choked full and imp mod before that. The dealer is asking 3500 euros for it. The gun has 30 inch barrels and detachable trigger. On the barrel it says G. Gamba Gardone VT Original Boehler. I know about Renato Gamba but G. Gamba i have no idea at all. Can anyone with knowledge give some info?

Thanks!
