As far as I know it is the original finish. My dad had it for at least 45 years and never did anything to it. The story I got was that he won it in a poker game in college. That was about 1955. He's had it ever since. The monetary value is not important to me. I would never sell this- but am curious what it could be worth. There is a big "but", however.
