I could help you out with a 2 3/4" Full choke barrel if interested. I have a plain barrel and a couple of vent rib barrels. The plain barrel has a fair bit of bluing rubbed off but the vent ribs have had some superficial rust issues in the past. I have rubbed the spots down but there is still some marring. The plain barrel is a take off from one I bought to use as a slug gun while the vent rib barrels came in a grab bag at an auction.
