What an absolutely fascinating thread. I have a Sauer & Sohn, Suhl shotgun with what I believe are Leupold Bernard barrels. However, there are NO marks referencing this. My information was obtained in a book in Cabela's gun library in Omaha/Lavista, NE; where I worked until retirement some 5 years ago. The gun was in "rough condition," and has been a project of mine for some years. Friends advised "get rid of the swivels, the gunstock, the cheekpiece, and see if you can get new barrels for it." Happily, I didn't do any of those things.
