Can anyone ID this barrel

[Medic187]

Gun (I’m assuming BP shotgun since no rear sight) had a broken stock and looked as though it was found in a barn. Surface rust all over but after cleaning the barrel I found some marks on the bottom and a (I’m guessing) copper ring for decoration. The single trigger was pin type through the stock with a back action percussion lock (seer missing).
