Looking for advice. I just received a musket from old family member. Stored away for last hundred years. Patina is almost black/dark brown. Cleaned away some small areas to find "Tower 1863" on side plate, "cw James Birmingham" stamp on stock. Rifle is 46" long overall. I went on line and found some info. I believe it is a confederate musket, 2 band. Most of what I saw were 3 band. I did not want to remove any more of finish until I found what I had. Questions are, should I refinish? Does it have more value than the many thousands of common rifles used during the war. Any help would be appreciated.
