Stan,

Your gun according to the Serialization Book should be a top lever hammergun with 30" barrels and a capped pistol grip stock.

Close up in focus pictures would be needed to show any damage. There is a member who makes new hammer screws so that should not be a problem. Any damage to the side plate would need to be fixed. Post some pictures for us.

Since you are in MD, I would suggest Dewey Vicknair at Vicknair Restorations in Lititz Pa for an overall evaluation of your gun.http://www.vicknairrestorations.com/...ns___Home.html
