I would appreciate some help in identifying this set of barrels, I have another set that I would like help with too and that will be in a separate thread. These are from the estate of Dale Edmonds and he didn't remember anything about them. They are 12 gauge barrels. I hope that the rather odd shape of the extractor may be a clue.
