I worked briefly for the Michigan State University museum gun collection and was told the tale of the Dr. who was taking a two year sabbatical in Europe and left a very nice minty collection of Sharps rifles with the museum with the provision that they could display them if they wanted to. The "Curator" of the time did display them by drilling two holes in the wood for dowel pins that mated to peg board. No input on what the Dr. said on his return. I imagine that there are collectors out there wondering why there are two filled holes in their guns!
