Tim,
I don't think you see wings below C grade. Your gun is a great one. Keith did a beautiful job on the stock. My C grade 10 gauge, 32" Bernard pattern bbls., has a top lever instead of a thumb opener. It is SN 9,645. It looks to me as if your 28" bbls. were added by the owner, who probably sent it back to the factory to get a set of shorter, lighter barrels for upland hunting. Buck Hamlin has great insight and knowledge about second sets of barrels. He can see things in serial numbers and their positioning that tell a story about the gun and its barrels to Buck's educated eye. You may want to contact him for his insights. I know we have communicated about your 10 gauge before. It is a dandy.
Rich
