Saw a 16 gauge 2F serial #453829 that had smokeless powder steel marked on the barrels. I have never owned an Ithica and this seems like it is in good shape. It has a ranger rubber pad that is detiorating, but that seems to be the only flaw with the gun. Does anyone know about these powder steel barrels? It has pointers engraved on both sides with a few stars engraved also. A metal release forearm. I just am curious about these barrels. They have a greyish/brown patina with no marks or dings.
