I just acquired a 12ga LC that has the Wildfowl designation. In reading the late John Houchins book I see that ALL Wildfowl guns were to 1. Be chambered for 3" and stamp so on the barrel flats. 2. Have the reinforcing lug behind the forend hook. My gun is a 2 3/4 and has no reinforcing lug! Any thoughts? Thanks in advance.
