c. 1824 Purdey 20g percussion fowler with Charles Lancaster Stub Twist barrels



The barrels are indeed 4 Iron (Turkish) British Best; 3 full scrolls between two 1/2 scrolls. IMHO they were Belgian sourced.
BTW Bro. Culver would see 3 'zipper' welds between each straight ribband edge weld wink



I wonder if the barrels were originally 'black & white' and intended for the North American market
