Moses Yoder
It seems strange to me that you would try to win this thing for many years, then finally accomplish that, then sell it. Really. One thing I have learned with rare tools I have sold, I always regret it. I spend the money, then I don't have either the money or the tool any more, and I can't just go buy another tool. I would suggest using it as a trap gun and having fun with it, then eventually passing it on to the next generation. It may not be worth much now, but I bet it will be in a thousand years.
