My 16ga with 30’s is graded and I’m not looking to sale, but I wish you luck in finding what you’re looking for. 30” barrels can be a hard find in the sub gauges. I think the Foxes represent the finest, most lively doubles made in the US. But since you are a collector, you already know all of that. Are you a member of the Fox Collectors? It can be a good place to look.
