In 1938 at ten years old, Gary Schlosstein discovered a Civil War musket in a used goods shop. He saved up his allowance until he had the three dollars he needed to buy the musket. Once he got the musket home, he loaded it with gunpowder, put a marble in it, and aimed it at his sandbox. He never did find the marble again. Fortunately, the musket didn’t explode, either. But that musket started a lifelong passion of collecting historical memorabilia. Over seventy years later, Gary founded the Castlerock Museum in Alma, Wisconsin, which specializes in arms and armor.
